I am currently training for the Trans Am Bike Race. About 4200 miles self-supported across the US. I am constantly researching every aspect of ultra racing, but I have not been able to find any clear advice on this question specifically. Financially I can’t afford to just kit out my dream machine. I saved for a year just to buy my bike in its raw form!
I train with power on a kickr, and I know and understand all of the advantages to training and even racing with power. However, is it possible, when you know that you will be on your bike for 16 or so hours a day for 2-3 weeks straight that HR might be enough data?
If the answer is an “absolutely not, you will be at a severe disadvantage.” What are some suggestions for best power meter options when ultra racing? Battery life and ease of changing / recharging are very important, while accuracy maybe doesn’t need to be perfect. I thought a single sided pedal would be an option, but damn they are still quite expensive.
Thanks for anything you got!
