I've been working in West Africa, with no climbing options, so switched to my usual alternative of running, which I've done a lot of over the years. Running maybe 5 day a week, mostly 6-9k as it's almost impossible to go further, for all sorts of reasons, mainly heat and humidity related.
One run last week, average pace as I was looking to go 8-9k, got to 5k and felt a pain in one calf. Thought it was cramp and slowed, but it didn't subside so after half a k more I stopped.
Rested for a couple of days but could still feel pain/tightness in the calf when testing running action, so I think it wasn't cramp at all. Rested a few more days until I could jog around the room without noticing it, then tried running again, similar pace or perhaps slower. Everything completely fine until 2k, when the exact same thing happened again, this time causing more of a slowdown, to a jog before no longer painful, so again I stopped.
I'm thinking it must be some kind of muscle tear but I've never had similar before. Any thoughts on what it might be? And how long to leave it before trying again?
