We were able to test two members of the team yesterday, Kelli and Emily. Using the CycleOps PowerTap SL2.4 (a wheel you can rent from
Rasmussen Bike Shop to do your own testing) we did a Critical Power test using 2, 10, and 6 minute intervals with full recovery between each interval. How this works: Each girl does her interval at maximum effort (time trial pace). We then extrapolate an average wattage for that interval as well as the highest heart rate achieved. Then, plugging the three interval results into a formula, we get a very well structured heart rate training zone as well as a series of power zones based on ride duration. If this is confusing you, no worries, seeing the results will make perfect sense of everything.

Using these results we can tell you a number of things including:
1. Kelli should take steps to building on her top end explosive power while Emily should work on her endurance.
2. The HR zones between two athletes of the same gender and same age is drastically different.
3. If these two were to race today it would be advantageous to use Kelli as a long distance attack or lead out and save Emily for the final climbs.
4. They both enjoy turkey sandwiches for lunch.
5. Emily’s critical power for an hour is 153, Kelli is 222. (Yet when you consider drafting and climbs their speed would be similar and one would likely not drop the other.)
Answering the nerdy questions before you ask.
Q: What is a watt? And what is critical power?A: A watt is a unit of energy that you can produce. Wattage is a plural of watt and is often called “power”. Wattage is to a cyclist like horsepower is to a car (in fact 600 watts = 1 horsepower). Critical power is the highest wattage you can maintain for a given time.
Q: Why did we choose 2, 10, and 6 minute intervals?
A: Because we wanted to test top end speed (2min). The ability to dominate a 2 minute effort is crucial in mass start cycling. The final sprint, Iowa climbs, the start of a break away, the first lap of a criterium. All of these efforts are roughly 2 minutes and the ability to perform at this length of time is paramount. We believe that anything above 10 minutes is more a test of mental fortitude that actual fitness. The formulated results our spreadsheet gives for any training time over 10 minutes are well within acceptable for anyone’s training standards.
Q: Why do the tests in that order?
A: You need a shorter and longer test to extrapolate decent averages. Doing the tests in this order (2min, 10min, and 6min with full recovery) is the best way to test an athlete in one sitting where the first tests will have the least effect on the subsequent tests. The 2 and 10 minute tests were to ensure our averages, the 6 minute test was to help better define the averages. While we prefer to do our testing in one day, you could do the test in two sittings, for example; do a 1min and 15min test on Tuesday and a 3min and 9min test on Friday… you may find a slightly better set of averages.
Q: Does anyone ever test themselves for an hour or more?
A: I’m sure there are some sadomasochists out there who would put themselves through that type of torture, but I would rather take a CP value from a really hard group ride or race.
Q: How do these women compare to pro women out there?A: Since 2008 will be Kelli and Emily’s first full year of racing they know they’ve got their work cut out for them when they race against some of the top dogs. But with these tests we can pinpoint their weaknesses and strengths early on, understand them, and build on them. So when race day comes they won’t be entirely caught by surprise.
Q: Who’s the strongest girl on the team?
A: We still have four more tests to take, but those numbers will only tell us who is best at taking tests. When a starting pistol is fired, a completely different monster will take over and these women will likely shatter many of their wintertime test results. Which is why it is very important to take some power analysis from your early season events as well. Nothing will ever push you as hard as mass competition.
Q: Why record things like food, stress, or fatigue levels?A: Because we want to chart every possible variable outside of fitness. Hours of sleep, hours at work, fatigue, etc can all affect one’s performance. On our next test if Kelli got 10 hours of sleep and didn’t have to go to work that day she’s likely to have a better result without actually having a gain in fitness. (For all you women out their doing this test it is especially important to record whether or not your cycle is at a point where it could adversely affect the results).
Q: Since when did taking tests become punk rock? A: Since we said so. Eat it.
Q: Can I get a copy of this test?A: Heck yeah!
HERE’S THE DOWNLOAD. We recommend that you record much of the same information that we did, and do the test in a manner so you can easily reproduce the protocol. We did the test indoors on trainers, that way we can recreate the same conditions a month from now (if you do the test outside then take note of route, wind, and temperature). Have fun!
We will be testing Maria, Ana, and Jane on Thursday. Stay tuned for those results!
