I started C25K back in June, but stopped in Week 3 due to knee injuries caused by going too fast too soon. I had some physio, took time to rest, and did the recommended stretches etc.
I restarted last month, doing the Week 1 runs at much slower pace than before, and only running once a week. So far so good.
Is it OK to continue the rest of the programme by only running once a week, on a Saturday morning?
FWIW, I also swim 1K twice a week before work during the week, and walk 2.5K twice a week at lunchtime.
