Just had a visit from the police (nothing to do with me but asking about a neighbour). The size of him reminded me of this thread, I am not sure he could have ran to the bottom of my drive let alone 1 & 1/2 mile.
C25k did not work for me. I know it does for many but I was just focussing on the time till rest and the dawdling to much on walk. It felt like a miserable / forced 15-30 mins workout.
I started just going out the door and jogging until it was uncomfortable and then walk-jog back home. My target was to go further before stopping than the previous time. I would not recommend this as it is not as controlled as c25k but it is better than never running if c25k does not work for you.
For me running beyond 15k is where things get serious and needs a degree of preparation. Running an ill prepared HM is not something I would want to do. Having a degree of confidence I can finish he distance a reasonable way ahead of the sweeper bus are things I want before setting out,
5k requires nothing more than some water after finishing. I do not need to take water during a run until 10k+ but will generally carry water over 8k+ just for comfort. Sports drink, gels or recovery drinks are unnecesary until around 20k distance.
