Well, after pushing too hard at parkrun I was in a fair bit of discomfort and spend all weekend worrying that I was injured. Major sulk.
However, then went for an assessment at our sports clinic at work (I work for an University). After a few tests, it was confirmed that there was no injury - just tired muscles from overdoing it.
Ummed and ahhed about whether to take a week off but thought I'd just gently try a run tonight. About 12 mins warm up then 25 mins running - no problem. All discomfort vanished.
Embraced my inner snail.... I was being passed by cyclists, runners, joggers, walkers, mothers with prams, old ladies on Zimmer frames. No matter.
So I'm still in running heaven!
In other news, my Garmin arrived (17 days after order, but that's another story!). Snazzy...
