After watching my husband in a recent half marathon I signed up for a 10k run in Dec. That gives me 8 weeks to go from nothing to 10k. I used to run but am currently overweight and old (55). Can I do it or am I setting myself up for failure? Any good running training apps? I've used C25K and liked the style but can't seem to find one that will do similar for 10k, just tell me when to run and when to walk on each run. I can download training plans but don't want to faff about with a watch while I'm running - it's hard enough without that. Any suggestions/support gratefully received! Thanks.
