Well I've completed the dreaded wk5r3 and about 13min extra ! Here's why . I useually use the podcast but decided to make my own playlist and use the new app on my I phone , all was well after 5 min warm up walk , Laura says she's with me & will let me know how far I've gone start running . That's last I heard from her ! I'm running to my playlist & after a while I'm thinking surely I've been running longer than 5min , after about ten min I knew I was on my own , so I kept running. & running then , wait for it , end of playlist there's 14 tunes on it ! But I kept on going for safe measure about another 3 or 4 min , I've totalled it & as you can guess ran quite a bit over 20 min . Ooh I feel as fit as a butchers dog , can't believe I've done it . My ankle isn't happy though. , knees fine , now it's right ankle .
