That’s how far Jayson Austin was calculated to have ridden on his second and successful attempt to set a new world record for Masters Men (35-39) distance ridden in one hour. It added a huge 2.676km (5.8%) to the previous record set in 2007 by Jason Sprouse of the USA.
It is also the second furthest ridden by an Australian, with Brad McGee holding the honour of the furthest distance (not sure exactly how far but it is something over 50km).
It’s also about the same length as this post, so be warned!
I wrote about Jayson’s previous unsuccessful attempt in this post: An Hour of Power, which has been one of the more popular reads on this blog.
So what went right this time? How did Jayson add a whopping 3.649km (8.2%) to his previous attempt where he managed to ride 44.668km?
As I have mentioned before, there are three things that primarily contribute to a fast time trial (or in the case of the hour record, to maximise distance ridden):
- Power to the pedals
- Piercing the wind (plus fast tyres)
- Pacing the course
OK, well let’s consider his first attempt at the record last year.
Power - Feb 2008
Average Power: 241 watts (4.0 W/kg)
Normalised Power: 259 watts (NP:AP = 1.07)
Jayson took quite ill in the weeks leading up to the event and he was clearly not in the form he would have normally expected come race day. In hindsight he probably should have postponed. However that is a difficult choice as the logistics to organise the event make that tricky. In addition, on the day the timing system failed and Jayson had to abandon the attempt after 5-minutes and do a restart. That certainly did not help his cause at all. Jayson also chose to use a gear far too large for his form on the day.
Average Power for his first attempt was 241 watts. Normalised Power was 259 watts, giving a ratio of NP to AP of 1.07. For an hour record attempt, that is a very high ratio and one would expect a very well paced effort on a velodrome would see that ratio being very close to 1.00.
Piercing the wind - Feb 2008
Using the data available from the SRM power meter on Jayson’s bike, I concluded his CdA (a measure of how slippery you are through the air) was in the vicinity of 0.190m^2. That is very slippery for a bike rider by any standard. So Jayson had a pretty slick set up and position. Riding 44.7km with an average power of only 241 watts certainly indicates he was piercing the wind just fine.
Combined with his power, the ratio that most determines the speed a time trial rider will travel at is their sustainable power to aerodynamic drag - FTP : CdA - ratio.
In Feb 2007 that ratio was 241 / 0.190 = 1268 W/m^2
Pacing - Feb 2008
In essence, in the context of his sub-standard form come race day, Jayson simply paced poorly, making the classic mistake of going out too hard and fading. Badly. Ignoring the pacing signals from his coach, this was well and truly demonstrated by the charts in the first linked post, showing how much he faded through the course of the attempt, finally hitting a brick wall at around the 45-min mark.
Breaking his average power down into 15-min sections shows the dramatic fade in power:
00-15 min: 302 watts
15-30 min: 272 watts
30-45 min: 242 watts
45-60 min: 151 watts
I suspect what Jayson did was to ride at a level he felt he would be able sustain but that turned out not to be the case. C'est la vie.
Using my pacing analysis models (something I haven’t written about in any detail here), I have rated Jayson’s pacing with a Pacing Score of 0.960, which is, in fact, the lower anchor point on my relative pacing performance charts (i.e. indicating very poor pacing). A best in class Pacing Score is 0.995 (with 1.000 being theoretically perfect pacing).
To put that into context, if Jayson had ridden with best in class pacing, even with the reduced power at his disposal on that day, he could have added another 1.5-1.6km to his ride distance. He missed the record that day by 974 metres.
These are tough mistakes to make and hard lessons learned. But we often learn more from having the courage to make mistakes. Certainly both Jayson and his coach would have felt a little burned by the attempt (what some may not know is that Jayson had, in training, already beaten the record, just not officially sanctioned with UCI supervision, electronic timing, doping control etc etc that is required for an official record to be set).
In the months following, Jayson’s riding, form and morale slipped somewhat and his coach (a friend of mine), who was moving onto other projects, suggested Jayson speak with me about taking him on and getting him back on track. So Jayson and I discussed where he was at and set ourselves the objective of having another crack at the hour (as well as other racing objectives along the way).
For me, what was going to be important was that Jayson demonstrated a willingness to learn from the mistakes made (both from the ride specifically but also in general). You can be sure that these lessons were not lost on coach, and I consider them to be a substantial contributor to Jayson’s excellent performance the other week.
The biggest failure this time round would not have been missing the record, but in repeating the same mistakes.
OK, so how did the successful ride compare?
Power - Apr 2009
Average Power: 302 watts (5.0 W/kg).
Normalised Power: 303 watts (NP:AP = 1.00)
That’s 61 watts (+25%) more than his previous attempt. Now that’s gotta help. How did he manage it?
This time round Jayson did not get ill before the event. Nevertheless he is still relatively prone to illness, niggles and for some reason, a little accident prone as well (he even had a crash a few weeks before the attempt which did disrupt preparations a little). Jayson also works a full time job, with a lot of manual labour required (he works in the commercial flooring industry). So the ramp up of his training loads were pretty carefully managed to avoid increased susceptibility to illness and at times recognise that his work was sometimes tough on his body and training needed to be cut back. Even so, there were times when Jayson would do more than coach liked, and guess what? – the niggles would appear soon afterwards and training would be compromised.
Over time Jayson really started to appreciate the sense behind carefully managing the training loads. It enabled consistency of training and from that follows a steady and sustainable improvement in form. Jayson told me his form “sort of snuck up on me”.
Of course I did not confine Jayson to just training. Racing was a reasonably regular part of the diet. Every rider needs that little extra motivation at times, and pinning a number on your back is an excellent way to do this. As well, in the final weeks before the attempt, we minimised his exposure to Sydney’s busy roads, with a majority of rides being either with me, a trusted mate, at Centennial Park, on the velodrome or on my purpose built ergobike, Thunderbird 7.
Clearly Jayson has an engine and can really dig out some excellent power at times. What he lacked when we began working together, some 40 weeks before his hour ride, was depth of fitness. Despite very low training loads, he is way too capable of putting the hurt on and suffering the consequences. For those that understand the numbers, his chronic training load (CTL) at the time we started was ~38 TSS/day.
At the time of his hour ride:
CTL: 86 TSS/day
TSB: +10 TSS/day (training stress balance)
CTL/ATL Time Constants: 42/7 days
I did not have Jayson doing huge volumes. What I did do was ensure Jayson was doing quality work. Good solid endurance. Plenty of sweet spot / tempo work. Threshold tolerance work. And during the specific race preparation period, high end aerobic power work and specific threshold work on the track bike and in aero position at the track. The limited taper involved cutting back volume while using short but relatively intense intervals at the higher end of his aerobic power level abilities.
Here is a comparison of his power last time and this time:
Piercing the wind - Apr 2009
OK, so I have already established that Jayson was pretty darn slick through the air. But was any further improvement possible? Well yes as a matter of fact. Some positional changes, a different set of aero bars (based on a British Cycling design) and use of double disk wheels resulted in Jayson’s CdA lowering to around 0.185m^2. That’s a 2.6% improvement. It doesn’t sound a lot but that is worth approximately another 420 metres to his ride.
Thoroughly checked to ensure full compliance with all UCI regulations.
Note placement of the SRM PCV under the saddle.
During training at the track, where possible, changes in position or equipment were compared to assess the differences. An alternative aero helmet was tried for instance and found to be substantially less aerodynamic than the Uvex that Jayson used. This is one of the direct and practical benefits of using power meters. It removes much of the guess work and objective decisions can be made based on the data.
So now Jason's FTP:CdA ratio is 302 / 0.185 = 1632 W/m^2
Even so, I would say that further improvement with his aerodynamics is still possible. There are still several minor details which, with enough solo track time, I would like to have tried and tested but they will just have to wait for another day.
Pacing - Apr 2009
Well I’m glad to report that Jayson now has the unique honour of topping the pacing league table, with a Pacing Score of 0.998, the best score I have ever recorded, as well as being the low anchor point (0.960).
Let’s just say that of the things that were drummed into Jayson’s head, pacing was what I was most concerned with. I knew he had the power. I knew he was slick. But would he be able to execute?
To ensure that happened, we did a lot of work in the weeks leading up to the attempt focussed on pacing. I developed a means to clearly communicate pacing information to him and Jayson began to develop an excellent “feel” for how to augment his effort ever so slightly each lap to maintain a sustainable pacing level. His choice of gearing was part of that strategy.
One thing went against the “conventional wisdom” – Jayson’s average cadence was 112 rpm. Conventional wisdom says Hour Records are all but set with a cadence of ~100rpm give or take 1 or 2 rpm. Bollocks to conventional wisdom I say.
We also knew that different environmental conditions would impact on the sustainable pace on the day and we trained on different days with subtly different conditions. On the day of the attempt I checked both the air temperature and air pressure and that would tell me what pacing would likely be sustainable (and what wouldn’t). Dunc Gray Velodrome is not climate controlled and the temperature can and does vary quite a lot.
For example, a 5C drop in temperature would reduce the distance ridden by ~ 280 metres and an increase in air pressure of 20hPa would mean another 315 metres lost. Fortunately it was not a cold (21C) nor a high pressure (1004hPa) day although it had been warmer in training. Also, we requested that all windows and louvres be closed so as to minimise any potential wind disrutption and to retain as much heat inside as possible (April is Autumn in Sydney).
Of course the athlete is the one that must make a call on how hard to go but I had developed a very good understanding of his body language and could tell when it was too hard. Jayson was never going to go too easy, that’s for sure. My main concern was keeping a lid on it in the opening minutes. Jayson was made well aware of the lap times and how that played out relative to the existing record. The pacing mistakes were made in training, and ironed out in training.
On race day, nerves and adrenaline took a hold (I expected it, heck coach was nervous too!) and Jayson’s pacing was a little up and down in the opening minutes. However he made rapid adjustments knowing full well what over cooking it would do. It took quite a while but once he settled into a rhythm, his pacing was metronomic. Average lap times around the 250 metre track were 18.59 seconds (not counting the opening lap).
We had planned for a couple of “rest” breaks, where he could sit up, stretch, relieve any pressure points for a lap or so but as it turns out he didn’t need that and remained firmly in position for the entire hour. At times he varied his pace a little, and sometimes pushed himself back in the saddle, which was quite deliberate and helped him to stay comfortable and keep his concentration going.
Here is a comparison of his speed last time and this time:
Thank you to:
Apart from Jays actually having the gumption to have another crack and delivering, there were many others involved in helping him get there and all should rightly share the success, including his former coach (hi Peter) who introduced him to training with power in the first place and showed what was possible, sponsors, the officials who helped coordinate the venue/UCI/ASADA etc, our club chief Mike, Jayson's family/support crew, Steve Hogg who was very accommodating with equipment and constant positional adjustments, training and racing buddies who kindly lent special gear (wheels, bars) for the attempt and rode/raced with Jays during the build up. And then all those that showed up to cheer him on!
Just six days after his record breaking ride, Jayson was knocked from his bike by a car while on a ride by a “hit and run” driver. Knocked unconscious and very, very nearly run over by another oncoming car, who’s driver managed to stop with the bumper bar over Jayson’s head, he is lucky to be alive. Jayson was admitted to Manly hospital and fortunately suffered no broken bones. However he did suffer from a sizeable haematoma and severe swelling of the thigh which required emergency surgery to open the leg (a fasciotomy) so that excess fluids could be drained and the swelling would not prevent blood flow. That was successful but now he has a large open wound which will take some weeks to heal.
He has since been discharged and it will be at least eight weeks before he can work or ride. As you can imagine Jayson is pretty pissed off about the incident but otherwise is in good spirits.
So now it will be onto the next challenge, getting an injured soul back to good form. That's something I have some experience with.
