Last October I ran a 10K steeplechase obstacle course. As well as hopping horse jumps we also had to leap over/fall in ditches and run though plenty of streams - as if this didn’t leave us wet and cold enough, it rained the entire time apart from when it was hailing instead. It was easily the coldest and wettest I have ever been and that includes the time I ran into the Firth of Forth in Scotland on New Year’s Day.
