Hi easy tiger I run with a club and we welcome all runners regardless of ability, which is a good job as I would find it difficult to do 5 miles in 40 min! There are a number of groups who do different speeds and there is always lots of encouragement. I had loads of support from my club mates when I was training for the marathon, which I finished in 5:27:25.
Couldn't find any milk thistle so settled for the innocent drink. I drink these quite a bit so should be ok. Also I'm blessed with robust digestive system, honed on kwik save's finest at university.
