Have just completed wk5r3 and feel great. It is hard to believe that only a few weeks ago I struggled to do wk1r1 - which took me about an hour to recover from, and also the problem I had with wk5r2.
Decided that early morning runs suit me best.
Up to now have been reluctant of buying decent tops in case I could not manage and gave up. But since I am enjoying the runs and looking forward to the next I have now got some tops with reflective stripes in preparation of the darker mornings.
