I have completed couch to 5k up to W5R2. I have enjoyed the challenge and was apprehensively looking forward to the 20 minute run today. Last night I started getting a scratchy throat and today have woken up with a cold. It is the sort that makes a day at work not fun but not bad enough to keep me off work. If anyone else has experience with this could you advise me if I should tough it out or take a rest day and come back to it later?
