I would agree that doing Barcelona will probably scupper sub 3 London. However ultimately it should be about enjoying what you do and if sub 3 goal is not critically important then go and enjoy! Ideally I wouldn't have done grizzly as prep due to injury risk but I love the race so didn't have to think on it.
I've been doing some yoga to help the aches as was getting a bit of a back ache. Seems to help - could be just the stretching which I'm normally v bad at.
nice to be home and running outside. Although today's run wasn't great. 10 miles, did first half too fast, tripped over a cone (v embarrassing and bruised leg) had a too thick top on and overheated. But av pace was marathon pace so not all bad!
