Was meant to go running yesterday but after walking all day my legs felt like they were on fire from that amount of exercise so pushed my run back to today. I've now just finished my week 3 run 3 and the gremlins were at my legs the whole run. It was really tough and kept trying to keep my mind busy and ignore them. I also had a peek at my next run (wk 4). It sounds intimidating, there is a lot less walking in that one!!!
