Tech Snippets. Hayden Roulston, Tour Down Under SRM data
Hayden is a world-class athlete and his ability to put out big numbers has been proven on many occasions. His silver medal at the Beijing Olympic Game’s in the individual pursuit is just one example. Another is shown in the image below. You can click the link for a detailed look into his figures for the day. Anyone who has used a power meter will understand that while his average for the stage is not huge, the normalised power or what he theoretically could have produced is impressive. Furthermore, his power output for 5, 10 and 12 minutes is of WorldTour calibre. We listed his weight in last year’s Tour Guide at 81kg.
Here’s a sample of the data:
Average speed: 39.7km/h
Calories burned: 3,766
Average power (normalised power): 271 watts (337 watts). This figure is impressive. A local Sydney criterium considered to be ‘tough’ is Heffron Park (Tuesday night) and this is a similar normalised power from an A-grader. However, this race is a handicap and everyone is expected to pull turns for the 33km race, not 153km. One of the quickest this year was when Chris ‘CJ’ Sutton (AUS) SKY, Graham Brown (AUS) RAB and Tom Leezer (NED) RAB showed up. They proceeded to lift the pace higher much higher than normal and in this race the normalised power from one of the riders in a National Road Series team was 339 watts. At just on 70kg the power to weight ratio is higher but this is for under an hour, in an all-out style crit, not a road race with a gradual build-up.
A major difference between an amateur and top professional can be seen in the 5, 10 and 12-minute efforts. This is reflective in the race where a breakaway went clear, established a sizable lead before the pace was turned up. Remember RadioShack-Nissan ripping the remainder of the bunch on the descent after the first Willunga climb? Hayden played a large role in establishing this group which saw the end of Matt Lloyd’s GC hopes.
Maximum power: 1,117 watts
5-minute peak power: 479 watts
10-minute peak power: 464 watts
12-minute peak power: 456 watts
The image below represents the data from Hayden Roulston’s SRM power meter. This particular file is from the stage to Willunga at this year’s Tour Down Under. Click the image (below) for a detailed view of Hayden’s ride that day. It will say “Alex Malone’s Bike” but unfortunately he is not capable of putting out this amount of power.
Here’s a highlights video which shows the split caused Hayden and his RadioShack-Nissan team over the top of Willunga on the first lap. Start the video at 10:40 to see the size of the group as it crests the hill then skip to after an commerical break at 13:20 to see what the team is capable of. Enjoy.
