It was my first - it was flat, so a lot of fast people wanting a PB (or just faster than me anyway).
A bit of a country hike to the swim start, but you wore shoes and a vehicle takes them back to HQ. The river swim was WELL COLD - but down river, and yes, very few people behind me, but who cares? A very pretty run through the grounds to T1, and then 2 and a bit laps of quiet country roads that came through the park each time, so good for spectators. (Bike route was a bit short by my reckoning)
The run route was lovely - 4 laps around the grounds, a bit off-road, but good underfoot.
Got a rather nice rucksak and a medal, but no goody bag or nosh after, but very enjoyable, and the other competitors I spoke to were really friendly (quite a few first timers like me). Oh and free, but very basic camping fairly near (but not quite as near as Outlaw).
Would definitely do it again
