I'm really struggling with this week. I ran r1 kind of ok but not entirely running for absolutely the full 25 mins (a couple of 30 second breaks for cramp) but 2nd run on Saturday and 3rd run today were both a bit of a disaster. Cramp got me in the 2nd run so have done lots of stretching and drinking (water) and giving myself some rest days but today I just couldn't keep going for some reason and so ended up doing a kind of off-plan interval session which felt much more comfortable. Maybe it's the heat?
So should I go back a couple of weeks and build up again, or just keep trying to achieve the full 25 mins? It's a bit disappointing to keep trying and not managing it (I'm being very careful not to use the f word!). I know that whatever I am doing is better than not going out but this is the first week where I've really doubted my ability and determination. Any thoughts/tips?
