Hi, I'm currently in Week 7, so running for 25 minutes which is amazing, I never thought I'd be able to do that. But, yesterday I had to really slow down to a fast walk because I thought both of my calves were going to cramp up, they were so tight it was painful - about 5 minutes into the run. Then today my left knee is really sore, under the knee cap, making the stairs difficult. Has this happened to anyone else, is it normal and should I just keep going, or rest more? Or any suggestions please!
Thanks!
