IRONMAN Leeds
This is England's only full-distance IRONMAN, which is most of the reason to enter it if you are based in the UK. The 3.8 km swim is in the lake at Roundhay Park, the 180 km bike heads out into the Yorkshire countryside, and the 42.2 km run comes back to laps around the park.
Yorkshire riding is honest work. The climbs are short and steep rather than alpine, they arrive repeatedly, and the descents between them are narrow enough to demand attention. Gearing that would be fine on a flat continental course will leave you grinding here.
Mid-August is the best weather window the region offers, which still means planning for rain and a cool lake swim.
The park finish is the compromise. A lapped run in Roundhay is not a city-centre marathon, but it puts your supporters in one place and keeps them there all afternoon.
