Really gutted to get a calf strain - was doing really well. Did the first 10 minutes and everything was fine ; then started the second 10 and suddenly felt a pain in my lower left calf. I slowed but continued and managed to complete the run. Then went to a body pump class - the trainer recommended a roller and showed me what to do so I have rollered the painful area. I hope I am ok tomorrow and can still complete run 3 on weds.
