I've still got my pirate tri suit somewhere in the loft. I would have thought my regular posting on tri talk would have excluded me from ever returning! I just kind of figured I'd bump into you all again at some Ironman, but you've not been back to IM Frankfurt which is where I have been for the past 3 years!
I did Brighton a couple of years back and did enjoy it. I would not call it a pb course though, and certainly.not flat. That first hill in the park is pretty serious in marathon terms and the drag up over the cliffs once you turn out of town at 6 miles is again not to be laughed at. There was a pretty nasty head wind from memory too, and I found the first half quite hard going. No issues with congestion once out of the park.
However, according to this, they have taken out the big hill at the turnaround, so things might be a bit better now than when I did it.
