I took this photo in 2005 at Kells Road Races. This was taken on the last lap of the superbike race.
On the previous race, a bike had spilt oil on the inside line. Guy Martin, in the black helmet, had led the race and at this last corner, Ryan Farquar, 77, went for the inside line and outbraked him to win the race. The dust in the photo is from Farquar braking on the sand used to cover the oil spill You can see how hard they are braking by how compressed the front forks are.
The circuit is 2.2 miles on closed public roads and is exhilarating to watch.
Canon 20d, 180mm, f11, 1/250. I'm sure I butchered it in Photoshop but can't remember how :)
