Rain is the new challenge. I’ve ran in a drizzle before many times and arrived damp. That’s no problem. But when it’s pouring, it’s a different “experience”. Something about the feeling of a wet blanket attached to your body is a real pain in the a**, even on a quick 1-2 mile run.
The nice thing about rain though is it makes you question your approach to life. It makes you question why you give a damn about being wet or why it even feels unpleasant for your clothes to be soaking wet. Monkeys and lions have been sitting in puddles of mud in torrential downpours for thousands of years. I would be hard pressed to provide any good evidence of why I’m any better than those two. It is true that I have read Nietzsche, but to most creatures in the jungle that makes me even less worthy of respect.
