The race has a very impressive looking tracker website. Let's hope it works (it didn't 2 years ago). My number is 5181.
Here in Ireland it might be worthwhile to keep an eye out for Gary O'Hanlon 59981. Update: A brutally hilly course on a hot day meant I didn't quite make the marathon - got caught by the catcher car just after the 40k mark. 23th position overall from just over 1400 runners.
