The length you choose will depend on how many kilometres you can run at present, but it’s a great idea to try and level up your running this summer. If you don’t run at all, being able to do a 5km is a fantastic goal. If you’re stuck at 5k, try to aim for 10k, and the same for a half-marathon and marathon. There are some useful programmes that can help you get into running. Couch to 5k or couch to 10k is one of them!
