I have done the week 1 run 5 times (almost 2 weeks of it). And I am now at a full 60 seconds on 3 of the runs, 50 on a couple more: i found my self stopping just before Laura spoke up and regretting it. One was only about 30, but the path is narrow down by the old mill, and too slippery to go round the lady with a cane and 5 tiny dogs zipping about on leashes without risk of some or all of us going into the River Kelvin! So the last run, since it was downhill anyway, i kept on a bit more to make up for it!
Sunday will be my wk 1 run 6. i suspect it might take me another whole week to really feel like 60 seconds is comfortable rather than just do-able.
