Running

[BigBrother]

Been trying to get back into running over the summer while the weather is decent. Weight shot up when I was doing my Masters so been working to get it back down. Cardio level is still decent, but my muscles begin to cry that enough's enough after about 10km. In my mid 30s and I have a perpetually tight left calf - park/grass running is generally fine, but I'm so wary of treadmill running because the muscle will just seize up and that'll be out of action for two to three weeks.
