Good evening amazing collective brain. As a COMPLETE newbie to any kind of fitness have just completed week 6 and cannot quite believe it! I am managing to keep good breath control but my calves are the muscle needing the most building and currently limiting my pace. Am completing the runs but it is slow - around ten or ten and a bit mins per km when sustaining over a long period like tonight's 25 min run. I have managed each run first time of asking so far so am wondering whether to try and get faster even if cannot sustain for the next few weeks, keep going as I am to try to complete then try to build speed or go back to week 1 trying to be speedier now can maintain longer. Any advice would be much appreciated as think will complete but at current pace will be miles from 5k in the 30 mins! Thanks so much!
