2026 Half & Full UK Ironman events

[Toyota_Crown]

@joex

Features a 1.2mi (5km) swim,

must be typo. I’ll drop em a line! It’s just a regular 1.9km sw1m, I diddit last yr.

FYI: On the 10th anniversary of the event, they were daft enuf to offer a 1-off full ironman distance option at Scorton. So they called it (confusingly!) “Double Steelman” . When I’ve begged for them to repeat this, it was a firm ‘No Never Again’, as it apparently was such a b@ll ache to organise / get marshals all day etc.
