Hi, I graduated nearly 4 weeks ago, but haven't run since. I tried yesterday/today, and after 5 minute warm-up, 5 minutes running at previous pace (1km in 5 minutes), seemed enough! Does stamina go so quickly? This article runnersconnect.net/running-... quotes "after 12 days, levels of enzymes in the blood associated with endurance performance had decreased by 50%" from published work (for already fit runners). If this is the case, how far back in the couch to 5 k programme do you suggest I go to regain original fitness. Week 5 started with 5 minutes of running, so perhaps I need to go back to that stage? I guess it's not going to do any harm!
