I know of a number of people who tell me that they run daily, but if anything, these course teaches you to take a days rest in between runs therefore my question here is what is the impact of switching to daily runs? Are those other people making a mistake in running that frequently?
Running after you graduate: I know of a number... - Couch to 5K
Yep! No need to run every day. Moving up to four runs a week nearly did me in so I dropped it back to three. I am 90 though!
Seriously, if you are a new runner, you definitely need the rest day to allow your body to rest and repair itself. I can't speak for seasoned, experienced younger runners but I think generally speaking on here we are new or returning runners
I would strongly urge anyone doing the C25K to only run when they are supposed to. Daily running is not a good idea at this stage, and it is really, really important to take the rest days. I hate resting, but it is soooo important.
Unless you are already pretty fit and used to sustained exercise, I would recommend, at most, alternating days. Once you graduate you will probably want to work on speed or distance and you will still be testing your body's limits so give yourself a break and always have a rest day. I thought I was a superhero after I graduated and actually increased my distances and duration by more than the recommended 10% and suffered lower back pain. I have done months of core strengthening exercises to pretty much eradicate the pain and am now much more cautious. I thought I was pretty fit, but learned otherwise. You would be better off doing your core work on your "rest" day and build up the strength required, especially for distance work. I have read about C25kers doing "too much too soon" many times over the past year. You have a life time of running ahead of you, so why rush, and not being able to run because of injury is very frustrating.
Good luck. Keep running, keep smiling.
Cycling uses some of the same muscles as running, but uses them differently. I find it good cross training and was at my fittest when cycle commuting for my summer seasonal job last year. See this wee article
