I definitely crocked my back a bit at Turnslack, my left ITB is still doing for too much work. To add to this my second covid jab caused such a bad headache that my back hurt all the way down.
Only managed one rep of Tinshill Lane and two of Carr Bridge Drive before i had to call it. It was a very flat session, just like the ones you have after a long lay-off. I think the covid jab has hit my aerobic performance.
