Jens Voigt & Ideas About a “Fairer” Triathlon
Last week the 43 year old cyclist Jens Voigt set a world record for the 1 hour ride. Voigt covered 51.115 kilometers and then retired. Voigt has had a long career near the top of professional cycling and avoided the doping scandals that have plagued cycling over the last several decades.
What Does Voigt Have to do With Triathlons?
The short answer is not much. Normally a performance like this is a lead into a discussion about aging, the history of world records, the role of technology in sports (he used an aero bike), or some other element of sports physiology. However, Voigt’s record got me thinking about what would happen if each element of a triathlon was designed to take about the same amount of time. Both the Olympic distance Tri (1.5k swim, 40k ride, and 10k run) and the Ironman distance Tri (2.4 mile swim, 112 ride, and 26.2 mile run) have bike segments that take about 50% or more of the total time for elite competitors. The swim segment also takes less time than the run for elites.
Three 1 Hour Segments?
So, what would happen if there was a triathlon designed around world records for the hour? The current world record for the hour run is just over 21km by Haile Gebrselassie. The best record I could find for the hour swim is 6135 yds (about 5610 meters) set by Robert Margalis in a 25 yard pool in 2007. The swimming record, while impressive, is likely soft in comparison to the cycling and running records that were set by truly world class athletes in their respective disciplines.
Based on these records (and some other back of the envelope calculations) perhaps something with a running distance about 3.8 times the swim distance would equalize those two triathlon elements. A biking distance perhaps 2.5 times the running distance would also seem reasonable. So how about a swim just over 5k, a 50k ride, and 20k run? These ratios are a start. To do this well one would need a detailed statistical analysis of a larger number of elite performances, but my guess is that such an analysis would lead to ratios and distances similar to the ones I have suggested.
Take it Indoors?
Why not also take it indoors and come up with something like the triathlon version of the Crash-B Sprints for rowing. These races are conducted indoors on rowing ergometers and a number of winners and record holders have impressive records on the water.
For the Triathlon the format might be an hour swim in a short course pool and distance run in an hour on a calibrated treadmill. The trick would be how to deal with the bike element indoors. I would use some measure related to average watts of power output per kg of body weight over the hour. I have seen varying reports of what Voigt did, but it appears that he averaged about 400 watts per minute. This works out to a bit more than 5 watts per kg.
Using the ratios I mentioned above, point scales and records could be established for each discipline. Perhaps a top score for each event would be worth 1,000 points. Such a scale could also be age and sex adjusted so performances could be easily compared for each competitor. Perhaps things could be more strategic by letting each athlete pick their own preferred order of events with a standard 5 minute transition period between events. Would most people do the swim second to give their legs a break?
Just a Thought Exercise?
So far this is just a thought exercise or perhaps the beginning of a barroom argument for endurance athletes. However, I would be interested in hearing other thoughts about how this might be done and if anyone is interested in sponsoring such a competition it would be easy to formalize the ideas outlined in this post. Finally, I volunteer to be the first commissioner of the “Three Hour Test”.
