Here I am on Week 4. Can't really believe it. Struggled with heavy legs on Week 1 and thought I would never get past it. Felt a bit apprehensive when Laura said we were going to be running for 5 minutes tonight - but although my pace was slower I only really struggled on the 2nd 3 minute run. Not sure why I get fatigued about half way through - then manage to pick up again for the last part of the podcast? Laura really knows her stuff doesn't she? Having some knee pain the day after - but think that may be down to my trainers. Have read some good advice on the forums as to what the cause may be and how to prevent it. As a treat for getting nearly to the half way point I am going to buy some new trainers. If I can do it - anyone can! Thanks to my daughter who is acting as my running buddy & helping me get through each run.
