Most runners’ favourite letters of the alphabet are P and B. Combined, they represent weeks of hard work, myriad miles in the legs and a decent dose of discipline. But while writing these letters on Instagram is easy, earning the right to do so is considerably harder.
For this reason, I was in two minds when the team at running coaching app Runna got in touch with a challenge: run 10K, as fast as you can, and we’ll coach you to hit a PB. On one hand, the challenge sounded fun, and a new PB never goes amiss. On the other, I would be signing up for several weeks of religious running, which could be tricky with my somewhat unpredictable schedule.
