I ran last night for the first time in a few months, so I’m feeling that combination of great but sore. I needed to get back into it, though. Luckily, my workplace is holding a fitness challenge just as they did last year. Randomised teams of employees from across the globe count up all the kilometers they run, cycle, or whatever, to see who can do the most in four weeks. It’s a fun thing, but most importantly it’s a reason to get out there and do something.
