The dead legs after the long running

The week started with me going to the club on Monday night, I wasn’t going to do much other than jog, so I could join in with the session and the warm up as usual then we got into the session, we did running to the first cone back we did this four times each time pick someone and running at the pace but as the night went on I started to slow down so I was glad when Sonja said we were finished. I thought I wouldn’t be able to walk on Tuesday but I was ok until I walked into town and back with my shopping and my legs felt stiff. I was ok on the bike. So it was back to the club on Wednesday night, did a warm up and then some circuits I was no good at sideways plank. We then did the second part of the session we did 12min of running in 2 set off 6min which took me about 2 min to get around the course Rob had marked out for us so that was 3 laps on each set of 6min at pace of 9min/miles so if was a rest on Thursday because I was busy other thing so I went for a run on Friday night I only managed 3 miles around the town because my legs were so dead
