Jack & Dawn here! We're doing the second in an occasional series of challenges. The first one was a weight loss challenge in which Jack took the spoils. Here, Dawn is aiming for revenge and to grind Jack into the Clumber Park dirt (never happen obv). Oh and with your generous help, we're hoping we can bag a grand for the very worthy MacMillan Cancer Support

UPDATE:

I really enjoyed it! Dawn was unable to run due to an injury to her foot which she picked up in the last few days before the race.

It didn't go to plan exactly, but not in a bad way. I started right at the back of my 'wave' and was forced to go slower than I wanted for the first kilometre or so. The terrain map on the website led me to believe it was all uphill for the first half AND tougher than my training runs had been, so I carried on taking my time to make sure I kept a bit in reserve. It turns out it was a fair bit easier than I'd been used to and I hardly noticed any upward trend. Anyway I felt great at 5km and picked the pace up overtaking around 20 people in the second 5km. So my time was a bit disappointing at 1hr 0m 36s. A good day however. Best of all, so far we've raised nearly £700 for Macmillan Cancer Support. If you want to chip in with a few bob more, apparently the page will take donations for another three months. Thanks to the generous souls that already raided their piggy banks - it's very much appreciated!
