She only went and did it again, halfway through the 8 minute run. I just had to yell out "NO!" and scared a load of dickie-birds... no one else out at 8.00 on Sunday morning. She first recommended heel strike way back when in week 2 or was it week 3 (how time flies). The advice on the NHS website is OK, so why can't they update the podcasts?
That aside, had a good SLOW run. Followed fellow bloggers' advice about going slow and their warnings about the euphoria after W5R3. Thanks guys.
While running I was trying to calculate whether or not I'd finish the last 5 min run before hitting the awful climb back up to town... Decided it'd be best to turn around after the middle 8 minute run and do part of the 3 minute walk in the opposite direction. As it turned out, the 5 mins were up 2 mins before reaching town, but since that's mostly in full view of the neighbours, I ran it... so 5+8+5+2 = a total of 20 minutes again (albeit with breaks).
