(Below's observation is intended as a humorous comment not in anyway meant to undermine any advice given by others on this forum.)
I am talking to you from a self imposed spell on the 'naughty step'. I have broken one of the major rules of anyone doing C25k and in the early times of their running career.
"What," I hear you ask, "Possible infraction could deserve such a heinous punishment as placement on the naughty step?"
Well to quote the mitigation I gave whilst chastising myself as Naughty Nigel, a name I have been given many times in my 67 years although my name is actually Niall,
"I so wanted to do parkrun when I was away and I made an honest mistake, it wasn't my fault I'd been ill and couldn't run before, ok you got me bang to rights gov!"
I think I've got off lightly especially as I missed the mulled wine and mince pies post run and after all I did run on two consecutive days.
Disclaimer; I fully agree with the 1 day rest between runs, my own C25k took 13 weeks because I stuck to it as well as not running whilst in pain.
Further details of my parkrun is in the replies on the below thread.
