I am a new to running overweight 57 yr old couch potato.... but I am actually enjoying myself. I have been following C to 5K for about 12 weeks now although for the last 4 weeks have been struggling with a viral chest infection so have been just doing what I can. The most I have run so far non stop is 15 minutes but am happy doing 2 x8 or 2x10 min runs with 5min walk in between. I do struggle with the heat currently so even though I have been doing the program for almost 12 weeks I have not made very good progress. Any tips for building up my stamina and coping with the heat would be much appreciated.
