The Heaton Park runs offer the choice of a 5k, 10k, or Half Marathon. Which is great and convienent if you have multiple people wanting to run different distances at the same time.
It also allows more marshalls to be on hand to help out!
But it's devesating completing 4 laps and passing the finish line eachtime.
Good event, good support, but I'm not sure I'll do it again(because I hate hills).
