The Peaks Challenge starts and finishes at Falls Creek. The journey takes you over Tawonga Gap, Mt Hotham and climbs the back of Falls. 235km, more than 4000m of climbing (146mi, 13,125feet). I live in the flatland so a trip to the hills seemed a very good idea.
It wasn’t an official training camp, just a DIY effort staying in caravan parks, the lovely Gayle as my support crew. It was an opportunity to try eating lunch during a ride and a chance to gauge the pace required to get it done in under 13 hours because if you can’t stay in front of the clock you will be invited to leave the course.
I had never ridden from the summit of Hotham to Omeo before. That was the only section that was a cycling mystery, the bulk of the route, including the big hills had been ticked off individually previously.
Day one was Freeburgh to Omeo. 102.4 km 2,221m of climbing in 5hr 39min including 20 min off the bike for lunch.
Day two started in Omeo and ended in Mt Beauty taking in the Back of Falls and Tawonga Gap. So, all on course but the final few kilometres in the opposite direction. 128.5 km, 2425m in 6hr 52min. Again that includes 20 mins off the bike for a salad.
When the big day comes I’ll need to put all that together and add another 5km! Not all kilometres are equal but the 5 missing from this exercise are flat. A very good thing.
The average speed for the 230 km was 18.472 km/hr which would get me in at 12hr 45min. I would certainly take that. Bad weather or a puncture would be all that it would take to do me in. On the day there will be opportunity for drafting on the flatter sections which offers an energy saving. There will also be the opportunity to make crucial mistakes. I will have to climb at my own pace not try to match the person ahead of me. Two and a half watts per kilo up the hills will get me there. It’s essentially no watts per kilo to come down. There are sections on what seem like down hills that require more than a little effort to get over. That is quite noticeable just after Fainters Falls on the way down from Falls Creek and again approaching Omeo and yet again heading to Anglers Rest between Omeo and WTF Corner that marks the start of the last major ascent.
And on that last major ascent there are a few places where 3 watts per kilo barely keeps the bike moving forward. I haven’t yet got off and walked – that would blow the time budget right out the window.
Here’s his video on the subject. No need to watch it unless you have a specific interest …
There is nothing in it that violates cycling orthodoxy which concentrates very heavily on carbohydrates. Most of what’s on the table is going with you on the ride – I’ll need a trailer!
I’m thinking this through with you as my sounding board. Please let me know in the comments what mistakes I’m about to make.
What are the requirements?
Hydration is clearly a must. I’ll put a second 750ml water bottle on the shopping list straight away.
There is a clue there as to my normal routine. Generally I drink before setting off and will not drink again in the next hour. I then start to sip occasionally rationing a 750ml bottle over about 4 hrs. I don’t bother to take a second bottle unless I intend to be out for longer than that. I arrive home under-hydrated and drink a liter fairly promptly. Not good enough, Robert.
There will be opportunity to refill the bottles at stops along the way and whilst stopped it’s a good opportunity to drink a bit extra. If you don’t need a pee from time to time or your urine is very orange you need to drink more water. The need is clear. The solution is straight forward. Drink little and often – it will be absorbed better. The aim should be to lose no more than 2% body weight. (Scales in the trailer?) It’s all about discipline.
Electrolytes. Salt is lost as you sweat. Sodium chloride is present in the sorts of things cyclists eat and drink and aids absorption of both water and carbohydrates. Back in my marathoning youth (30’s actually) Staminade was offered at the drink stations and actually started to be palatable after about the half way mark. Overall, though, electrolyte replacement is way oversold. So forget the potassium and magnesium. A chocolate milk at three stops and a couple after the event and a gel or two here and there will take care of the sodium and help with rehydration.
Energy is the big one. Looking at the Calories that Strava thinks I’ve used for a couple of my toughest rides leads me to believe that I’ll need about 460Cals/hr. The physiologically average guy has about 80g of glycogen in his liver and 500g in his muscles on the starting line, say 600g equal to about 3,000Cals. This is increased in the trained athlete and boosted by carbo-loading but remember that muscle glycogen can only be used in the muscle that it’s stored in. The spare glycogen in my impressive lats can’t be borrowed by my exhausted quads. Once your leg muscles are empty you’re knackered, once your liver is empty you’re comatose by the side of the road. Bonking is the cyclist’s nightmare.
I could be in the saddle for 12 hours or more so the total Calorie requirement is about 5,520 equivalent to 1.1kg of carbohydrate (a deficit in the order of 500g – 600g COH – if I can get that amount in I can be comatose at the finish line clutching my finishers jersey).
The line of reasoning so far is well known to cyclists but things are not as bad as they seem because there are two other sources of energy – fat (by β-Oxidation of fatty acids), which I have plenty of and protein (by gluconeogenesis) which I would rather not use. I’m on a low carb high fat diet. It has helped me slim down considerably. I usually train fasted or with a low carb biscuit for breakfast. I commonly allow myself a banana a couple of hours into a long ride (>100km). This is supposed to have brought about some fat adaptation. I will be able to mobilise fat for some of the energy needed.
There is absolutely no doubt that the consumption of carbs during an event delays the onset of fatigue and that post event carbs aid in recovery. I will be consuming carbs during and after the ride.
This approach is sometimes referred to as a “train low race high” strategy.
The coma can wait until I’ve had a few beers.
The athlete can absorb about 60g of glucose per hour. Fructose is absorbed by a different pathway so another 30g can make it to the bloodstream. One molecule of common or garden table sugar breaks down readily into a molecule of glucose and a molecule of fructose. So 60g of sucrose plus 30g of glucose per hour is as much as you can do to offset the energy expended cutting the deficit in my case to just 10Cals/hr.
If you’re going to drink it an 8% solution is optimal. That is 60g in a 750ml water bottle. Sports gels tend to contain about 20g per sachet – I’ve yet to try one. Dates have about 5g each, bananas have about 20 – 30g but can become inedible after traveling too far in the back pocket. Jam sandwiches anyone?
Supplements. Welcome to the Essendon Cycling Club. Caffeine, good stuff, well known to enhance fat utilisation and enhance athletic and cognitive function. The effect is greatest in the naive and almost too small to measure in people who consume it daily. I’ll almost certainly have two long blacks before setting off – it’s what I do everyday. I don’t expect it will benefit me much during the ride.
Beetroot concentrate is a new one to me. According to Sports Dieticians Australia it works because it’s loaded with nitrates which are converted to nitric oxide (by oral bacteria no less) which cause some vasodilation. There is a Training Peaks article <HERE> as well. The main benefits claimed are a delayed onset of fatigue and better performance at altitude. A concentrate taken 2 to 3 hours prior to the event might be the go or you can juice a whole bunch of beetroots. Don’t clean your teeth though – just turn up at the start line looking like Dracula. Viagra works by the same mechanism, it would be way more convenient – could be the new wave.
Analgesics are also on Dr Lane’s list. I can’t imagine they will give enough benefit to be worth taking.
There you have it, eat drink and be merry – it ain’t an exact science.
The Peaks Challenge at Falls Creek entails more than 4,000 meters (13,100 feet) of climbing. Living in the flat land makes it hard to prepare the legs. One answer is an indoor trainer that can simulate the resistance that would be experienced climbing hills. I settled on the Tacx Neo 2T and with the help of Youtube got it up and running. I’m currently enjoying, if that’s the right word, a one month free trial of the Tacx software.
Here’s a shot of the pain cave …
I’ve repurposed a superseded lap top and thunderbolt screen and added an ANT+ dongle to the computer so that it can read my heart rate monitor. In this shot I’m setting off to climb the Jaufen Pass. The video advances to match the speed that you’re making whilst the software adjusts the resistance to reflect the gradient.
Here’s a screen grab nearing the top of the pass …
On the left of screen you can see speed, power, cadence, heart rate, time elapsed, the gradient and in the tiny letters the most important information is the distance to the top.
The real Jaufen Pass is in the Alps in the far north of Italy. On the Tacx the ride to the top is a little over 15 km and climbs 1,087 meters. Average gradient is 7.2% and it maxes out at 9.4%. You can continue down the other side but I can’t for the life of me see why you would, you reach impossible speeds with no effort and round corners in a fashion that would be lethal in real life and are too dizzying to look at on screen.
How does it compare with the real thing? It certainly feels pretty realistic and I think it will substitute well for the missing mountains.
As well as a library of videos there is a workout section where you can set up an interval session with control over gradient if that’s your thing and there’s a built in ramp test and FTP test.
The trainer will work with other apps such as Zwift and RGT. They have free introductory offers that I will probably make use of before choosing which way to go in the long term.
Meanwhile there are 54 days until the big event which equals four Jaufen Passes plus a whole load of connecting asphalt.
The week was invented by astronomers not physiologists. It just divides the lunar month into neat quarters. From a fatigue management perspective shorter regular blocks suit me better than a seven day week. The biggest problem is that the calendar and the program don’t stay in sync. If Wednesday is the group ride and Saturday is race day the system runs off the rails.
Within the block I like to ride hard then easy, easy, hard then the fifth day is a day off. There is nothing sacred about that order so that’s where group rides and race days can be accommodated – just change the order when necessary. The day off though is well worth preserving even if it means ending a block early.
Occasionally it runs to plan and last week a block looked like this …
The Training Stress Score (TSS) is one of a number of tools designed for quantifying training load. It uses power, time and intensity. Riding flat out for an hour would give a TSS of 100 and leave you gasping on the side of the road. Riding at lesser intensities for longer periods will enable you to achieve higher scores and still be able to walk!
Strava has a similar tool called Relative Effort and my Garmin Watch comes up with Training Effect. Today’s ride for example had a TSS of 154 or Relative Effort of 147. Training Effect in the Garmin universe is expressed for Aerobic and Anaerobic scores separately 3.6 and 1.1 today.
A TSS of less than 150 is considered Low Intensity, recovery will take less than 24 hours. 150 to 300 is moderate, you should be fit to train the next day, over 300 is high and some residual fatigue may last 2 days. The Peaks Challenge will likely generate a TSS over 400.
A hard day may be a long ride, a big climb, intervals or hill repeats. I’m probably as guilty as anyone of making my easy days too hard and my hard days not hard enough.
My Garmin Fenix6 watch gives me access to a coaching program. It’s an odd situation being coached by your watch. It has no idea of my goals. Tends to suggest workouts that aim to improve functional threshold power and criticises me frequently for a lack of anaerobic effort. For someone preparing for an event that will have me in the saddle all day long rides are essential. The watch often dismisses these as unproductive. Given the money I paid for it I think it should show its owner considerably more respect.
I never was very coachable. At least the watch doesn’t shout at me when I ignore it.
An athlete should do the least amount of the most specific training that brings continual improvement.
In other words specificity and efficiency. What you can do this week depends in the main on what you did last week and the week before. If the objective is an endurance event and you aren’t confident on the basis of what you did last week then you need to do more this week. If it entails a great deal of hill climbing then you’d better climb some hills.
The other side of the coin is the more you do the more fatigue you accumulate. So I need to increase the training load but allow sufficient time for rest and recovery.
A training plan seems a good idea. Bicycle Network are the organisers of the Peaks Challenge and they offer three training programs devised by Dr Stephen Lane. It’s suggested you make your choice based on how much time you have available in your regular week. The least, perhaps the most efficient, calls for 10 hours a week, the biggest for 16.5 hours a week. I downloaded the intermediate one aiming for 12 hours a week.
They all give you a 16 week lead up to the event. Each starts with a measurement of your Functional Threshold power (FTP). Workloads are specified with reference to your FTP. They call for six days training followed by one day off. Hard days alternate with easy days and the fourth week of each block is an easier week. Long rides are prescribed for the weekends. Finally they wind up with a taper. Dr Lane has more advice and encouragement in video form all of which can be found <HERE>.
At the core of all three programs the quality work is much the same. Extra time in the more time consuming programs is largely more long slow distance. Up hill interval training figures prominently.
The programs have been designed to suit working people. They stay in sync with the calendar and don’t bite too deeply into weekdays.
The guru of my running days was Dr Ken Cooper. In his view exercising 5 times a week was the optimum. The additional benefit from a sixth session wasn’t great and came at the cost of possible injury and increased fatigue. In those dim distant Marathon running days there was never a time when I arrived at the starting line with as much training behind me as I would have liked but I never withdrew from a race (nor did I ever win one!)
Given the entrenched belief that six days in a row is too much and the fact that I’m not a slave to the calendar I have opted for working in 5 day blocks – Hard day/easy day/easy day/ hard day/day off. The second easy day includes a weights session.
The base that I’m coming off has been fairly consistent over the four months August through November with an average weekly volume of 365 km and 2,040 meters of climbing. Time invested has been 16 hours a week. In December I made a serious effort to increase the climbing, time stayed about the same but I climbed 3,120 meters a week, distance was slightly down.
I have no mountains on my doorstep so 15 minute intervals up hill pose a problem. The best hill in the neighbourhood offers about 5 minutes of climbing. I’ll cover the solution to that problem in a future post.
I also have a few treats lined up for myself to spice up the training.
I recently bought my self a Garmin Fenix6 watch. It measures various fitness metrics, tells me the weather, plays music and also tells the time. It has other widgets too including a compass. I bought my dearly beloved one for Christmas. Here they are looking north …
I haven’t seen her since.
I haven’t had the pleasure of playing in a Christmas concert this year because of the plague (the first horseman of the apocalypse?). Despite the fact that I am a heathen I do look forward to the carols. This is my favorite …
I have seen the Peaks Challenge describes as the hardest one day mass bike ride in Australia. My mother would have suggested I was trying to run before I could walk. The prize for those that complete the 235 km and 4000 meters within the 13 hours allowed is a cycling jersey.
Preparing for any endurance event requires the outlay of emotion, time and money. There is a gulf between romantic notion and reality. To arrive at Falls Creek in the sag wagon would be to drop right into the gulf … public humiliation and no jersey. What makes me take the gamble?
It’s not entirely a leap in the dark.
Experiment number one. 200 km ride.
This on a fairly flat course.
Nutrition – 2 bananas 1 litre of water.
Results – Average speed 24 kph, sore bum, sun burn.
Lessons learned – sunscreen, more water.
Experiments 2, 3 & 4. Ride up and down Mt Hotham, Falls Creek and Tawonga Gap.
These are the three major hills on the route. Each is a worthy challenge in itself but I made it to the top of them. Falls Creek from WTF corner to Mt Cope is the toughest and that’s the one that comes last!
I’d ridden most of the course in segments before shelling out the entry fee and booking accommodation. Can I put all the segments together in the allotted time?
The hardest ride that I’ve done so far is Omeo – Falls – Omeo, 150 km, 2,400 meters of climb. Lets call that experiment 5. It took 7hrs 30min at about 20 kph. If I could hold that pace the ride would take 11hrs 45min. That doesn’t account for all of the 4,000 meters. Let’s assume that meters climbed are far more influential than kilometers on the flat and divide the time by 2,400 and multiply the result by 4,000 we have a prediction of 12hrs 30min.
It might be possible. The job in hand is to make it probable. Climbing is the key. There are 74 days.
I just submitted my entry for the 2021 Peaks Challenge at Falls Creek. It’s run by Bicycle Network and this is how they describe it …
Peaks Challenge Falls Creek is a 235km ride with 4,000+ metres of climbing, set among the backdrop of the beautiful Victorian Alps.
You’ll tackle the ascents of Tawonga Gap, Mount Hotham and finally, ‘The Beast’ that is the back of Falls. The back of Falls will hit you like a tonne of bricks. With 200km in your legs, you’ll quickly learn why the first pinch is called WTF Corner. It’s a steep and relentless climb with little reprieve.
D Day is Sunday March 7th.
The challenge must be completed within 13 hours or they will cart you off the course in the sag wagon. It is further than I have ever ridden before and entails ascending up half an Everest. So you see I have set myself up for a very public humiliation.
Success depends on loading the legs and I’d better get cracking with that soon! I’ll share my preparation. If you are inclined to join up here’s the link BicycleNetwork.
