As most of you will know Tiffany Cromwell won Omloop Het Nieuwsblad last weekend and I had the opportunity to interview her a few days ago. I thought it would be interesting to do an analysis of Tiff’s SRM data from the race to put into perspective how good these girls are. Tiff was generous enough to oblige and send me her files. I’ve ridden with Tiffany and some other top women cyclists in the world and let me tell you, they’ve given me a whoopin’. This one’s for you power geeks out there. Have a look and don’t let the graphs intimidate you …
I asked Helen Kelly of Kelly Cycle Coaching (Melbourne) to help me with the analysis since she trains all her athletes with Training Peaks and is very familiar with the software. Not only that, Helen use to race at an international level and in the final race of her professional career, she was in a breakaway with Tiffany Cromwell as a young amateur at the Bay Crits (the Geelong hot dog circuit on Richie Blvd). They both stayed away for the entire race and Tiff attacked on the bell lap but Helen got to her by the final corner and just came around her moment before the finish. Helen was at the end of her career, Tiff was at the start of hers.
Anyway, back to Tiff’s power analysis. A few facts and observations:
- Tiffany weighs around 49-50kgs.
- Tiffany’s threshold power (tested in January) is 229 watts. This equates to a threshold power of 4.6 watts/kg.
- We’ll see male pros at the top of climbs with threshold power levels of 6.2w/kg, and back in the day it was closer to 6.9w/kg.
We can also see from the charts below a few interesting things:
Tiffany appears to be very good at keeping her nose out of the wind, because she spent 25mins below 60w and 30mins at 60-120w (i.e. in her recovery zones). This basically means that she was able to conserve a lot of energy when she could. Even more so, with her overall average numbers being so high, it shows that when she was going hard, she was going extremely hard! For 73 minutes she was over her threshold power.
Another thing to take into account are the cobble sectors and how much more effort they require than smooth roads. Also keep in mind that the point of racing is to conserve as much as possible until the decisive moment. Only use what you need and save everything for the finish. If you expect higher power figures because you’re use to hearing the men’s wattages, keep in mind through all of this is that Tiffany weighs only ~50kg.
Let’s get more into these power stats during the key moments of the race.
