Hi all just completed w3r2 and breathing felt fine however I'm struggling with my legs. I know its early days for me but When I start I can't seem to get into a good running technique. My legs are everywhere. Heels hurt. Slamming etc. By the last run of the programme I feel great. Get into a good stride. No pain and feel light on my legs ?? Why at the end? Do most of you feel like this. I'm wondering whether a longer warm up would help.. my physio mentioned doing the 'pose' running style but struggling with this when I slow down.
