I'd just wear a Casio for sports like that. There are some terrific Pathfinders that have brilliant features like barometric pressure (i.e.: is it going to rain on your parade), elevation, countdown timers, compass, multiple time zones, et al. The latest generation is solar powered. I love my old Pathfinder, but mine is the pre-solar version and it takes something like 5 batteries. I used mine in the military--it's a very durable watch, and despite the abuse it only has little bits and pieces missing here and there. Despite this, all functions work perfectly. Anyway, perfect for a cyclist IMHO.
