Trotters Mark's run

Ran to trotters from home. Great running weather with the overcast & light drizzle. I've never done this run before & it was tough. The course is 11.6k but we ran about an extra 2k. Also lots of hills & steep hills at that. Was doing ok until the speed camera then just starting to feel leg niggle a bit & could feel a blister happening on my left foot so I just backed off. Reckon we ran 13.5k & was done in about 1hr. Finished with the run home
So about 15k done & a blister to go with it
