I ride my bike to work every chance I get and it is a 30 mile each way commute so I only don't ride when it is supposed to rain. I've done a pretty good job of making calculated risks for rain with the two weather apps I have. I basically look at the 8am and 5pm hour to see if or how much a probability there is of rain, I check the night before and the morning before I leave. I had a pretty good run going but then I got rained on today luckily no high winds or major storm but just some annoying rain. My basic rule is that if there is under a 50% chance of rain during those two hours, and I factor in the odds before and after too, then I ride and if over I don't. How do you make your decision of whether or not to ride to work?
