I'm midway through week 6, taking my time due to shift work and today is a right-off for running as I've just finished nights and can't get off the settee!
Advice on here led me to get proper gait analysis and running trainers and stick to proper stretches after runs and on days off. My cramps are no longer and my bad knee doesn't now hurt and I can focus my mind elsewhere and just run. So thank you peeps.
If anyone is struggling with cramps and aches like I did, my new trick is a few yoga stretches before a run as you can feel it working and they are so easy to do.
Keep up the good work peeps and thanks for all the support!
