Sorry to read about so many injuries in here. I hope they're soon in the past. I guess if you had to have an injury, midwinter is probably the least disruptive time of year for many(?).
For me, I've been blighted by injuries and illness for quite a bit of this year: Covid 3 times, a couple of chest infections and then recently (and currently) a couple of cracked ribs. Also, insane working hours.
Add it all together and you get very little running.
I'm pleased to have got out for a gentle 5-miles this afternoon - my first exercise of any kind in nearly a month. It's very frustrating when your fitness drops to near zero but I guess you just have to suck it up, be philosophical about it and crack on!
