As triathletes, many of us feel compelled to sweat the small stuff during training, because - let's face it - on a long course the small stuff can be the difference between a PR and a DNF for some folks. I'll freely admit that I'm a numbers nerd. I spend hours analyzing things like my pre- and post-workout calorie intake, and my heart rate profiles from the day's training. Does this make me a better athlete than any of my peers? Absolutely not. However, it does keep me on track and helps me (at least mentally) improve over time.
The one elusive factor for me has been quantifying my power profile on the bike. Like many others out there, I don't feel that I'm competitive enough to lay down thousands of dollars on custom power equipment. However, that's not to say that obtaining power information would be of no use to myself, or to other AG'ers trying to improve their performance on the bike. Aside from the $$$ issues, there is a substantial amount of effort that goes into installing/tuning/maintaining power-specific equipment. Therefore, I ask the question, "What's it worth?" What's the value of that information versus the cost of that information? Call it market research. Call it personal interest. I think it's a very valid question - especially for people that have an appreciation for the dollars-and-cents price of performance.
If someone proposed to you a power-sensing device that integrates with your existing setup and a modest cycling computer (<$50), how much would that be worth - the equipment AND the information? Now, can it be done for that amount? More importantly, can it be done EFFECTIVELY for that amount? My goal is to find a solution to the latter question.
