Be ready to chafe. A lot.

The most pain I felt in training was not in my knees, not in my feet, but under my shorts. Apologies but this is just something we have to talk about. If you don’t prepare for your runs with some anti-chafe solution, you are in for it. Seriously, nothing is worse than hopping in the shower after a run and yelping in pain when the water hits your stingy bits.

My advice? Buy some anti-chafe cream and apply it liberally. Before things are a problem. It might feel weird to coat your undercarriage with creams and lubes before you run, but you will not regret it. Lather it on like Wendy Peffercorn lathers on baby oil.

Body Glide and Zealios Betwixt are my two favorites — put on a healthy dose of Body Glide before your run (it’s less lathery but works better than most creams I tried) and bring along a packet of Betwixt for when you start to feel the heat on your skin at mile 10.
