So I'm continuing on alternating days of running and riding although I have picked up a bit of a niggle. A dull pain behind the knee. It came on during Saturdays session of increasing pace 500m efforts. I probably should have cut it short but I wanted to complete the session and get my legs moving faster than they have of late. It didn't feel too bad but I took a rest day Sunday.
I managed an easy jog yesterday and a longer ride today at medium effort - apart from the climbing finish. The ache behind the knee is still there but not too bad. Maybe another rest day tomorrow to let it settle but we'll see.
