Ok, I'm shattered (too much work, not enough sleep this week), have eaten like a cookie monster (due to same), it's quite hot outside (by NWEngland standards anyway) and my legs are creaking, but I did do it - all the way to the end. And I had some pretty serious doubts as to whether I would manage till the end of the second 3mins. I found the bobbing head tip very useful and also fixing on a point (clump of dandelions, fence post) quite a way off in the distance, and working my way towards it, and then past it to a new one...
Feeling just a little bit smug - even though I look like a frizzy-haired beetroot.
