I ran every day in Janathon, but am not intending to run every day in Juneathon. Exercise, yes. Run, no.
So why, after cycling to work and back, did I dash upstairs, chuck on my running kit and go out for a (turn over now all you compulsive rounder-uppers) 0.98mile run?
It’s the Juneathon effect. There’s no other explanation.
