I did the 10 miler last year and the 10k this time. This is the event that got me back into running after a break of about 10 years. It’s really fun. Don’t be put off by the mud and the river crossings, they aren’t bad at all. It is a very scenic, interesting course tucked out of the way and this is pretty much your only chance in the year to run it. There’s even a ruined Roman city that you run around.
