Running..in the rain

The tough decision for a runner is whether to go out to run when the weather appears to be suspect and there are all indications that the clouds might erupt into rain. After having gone through this situation many times, I have learnt that the best decision is to go out and run- and the a priori probability of rain coming down during the run is 50%. I did go out today in such conditions and I ran into the 50% chance that the rain would come down. It did, and I ran to a place where I could take shelter until the rain slowed down to a drizzle.
