Finished my couch to 5k today. Whoopie! Achieved it before this year was out and before starting my new hectic job on 2 January. My challenge is to work towards actually running 5k in 30 mins. I haven’t measured my lengths sine I discovered I was doing 3.8k at 25 mins as I just wanted to take it step by step. Any tips on how to work to actually running5k in 30 mins?
