Hey rizzee and welcome to the thread
You've an exciting time planned with a first half and first full marathon. Your goal is definitely achievable for the half I would say, judging by the PBs, and probably well under!
I think I saw on the Random questions thread that you are going to follow the Boards plan? What would say your current mileage per week is roughly?
Great that you are sometimes running 4 times a week. I would suggest you try to get into that routine weekly before the plan starts in June.
Thank you! It's not great to be honest. Only 20-30KMs but I obviously plan on upping that and following the beginners plan in the OP.
Thanks for the advice
Staff Relay Race today, I'm looking for a sub 25:30, did 23:01 last year but I had a little niggle in the ankle the weekend so haven't trained how I would have liked.
