I have just discovered this community!!
I am currently on the couch 2 5k app, to help me get back into rnning after a couple of knee injuries and then laziness.
I am on week 5 at the moment, so I will soon be graduating and looking to get back into running and increasing my pace.
Though to be honest the biggest thing I can do to increase both pace and stamina is to reduce my excess baggage around my waist!!
