Today I managed Week 5 run 3. Was pretty worried about it, as I felt the jump to a 20 min continuous run was a big one ! partly got through it as I'd read posts here that talked about the training was designed to build up to this, and therefore totally possible to do.
Done it !! When I think about when I started this, and I could only run in 20 second bursts, then I've come a long way !!!
Decided to stick to my normal route, rather than a new one, and it worked fine.
