I did c25k a while ago but never fulfilled the parkrun ambitions
then winter arrived and I got lazy! The next spring I tried again - 2014 - but never completed the programme. So here I am again for attempt number 3. I went out yesterday for a slow run and lasted twenty minutes, but another lap of the block would probably have required some walking or hospitalization 
So I wonder if some running experts can advise? Do I start c25k again? Start it partway through? Increase speed first then distance, or build up time then speed or running? I would love to complete a parkrun I'm under 30mins next month which may be too ambitious but is a lovely thought !!
