I was in London for the past week and definitely tried to take advantage of it. I ended up running a lot because there were pretty great paths on both sides of the Thames. I ended up doing a total of 33.5 miles and felt pretty great. I also went to workout with Project Awesome London on Friday. They were an awesome group! Definitely live up the name.
We were doing sprints up and down Primrose Hill, doing exercises in between. It was definitely a bit rough because I don't really run hills that often (and I had to run 3 miles to get there). The best part was that the hill gave a great view of the London skyline.
If you're in London, I highly recommend hanging out with them. They were seriously so much fun.
