The Isle of Man TT is the most famous — and most dangerous — motorcycle race in the world: a 37.73-mile lap of public roads over the Mountain Course, raced at average speeds above 135mph between stone walls, hedges and houses. The next TT is expected in late May and early June 2027.
The 2026 event was one of the most weather-disrupted in modern history: only four of the eight scheduled races were completed, Dean Harrison was declared Senior TT winner after a single lap, and Michael Dunlop still extended his all-time record to 36 wins. The Sidecar class was suspended during the event on safety grounds, with a review now under way.

How to bet on Isle of Man TT
TT betting is built around race-winner markets for each class — Superbike, Senior, Supersport, Superstock and the new Sportbike division. Fields are small at the sharp end, with a handful of genuine contenders each year, so winner markets tend to be short-priced and rider head-to-head matchups often offer the more interesting angle.
Form at the TT is intensely specialist: course experience counts for more here than anywhere in motorsport, and newcomers — however decorated on short circuits — almost never win. Qualifying week speeds are the best public form guide before race week.
One unique TT factor to respect: weather. As 2026 showed, races are routinely delayed, shortened, rescheduled or cancelled, and bookmaker rules on postponed or shortened races vary — check how your bookmaker settles declared results before betting. And as always, bet for fun, never to make money.
