TT City Run

The TT City Run is a multi-distance running event in Assen that forms the opening of TT Week and is organised by Stichting de Asserstadsloop. The event (TT City Run) combines laps on the world‑famous TT Circuit with a finish in Assen city centre and offers options for children, recreational runners, competitive entries and team formats. The organisers highlight community partners and a charity partnership with Energy4All and provide provisional course maps and event updates on the official site as the final programme is confirmed.

Distances range from short kids' runs through recreational distances to a separately organised TT Marathon, with additional formats such as TT Circuit Laps, a Business Run and a College Run. Registration is available via the links on the official website (registration uses atleta.cc links) and there are shirt pre‑order windows and donation options during inscription. Final start lists, wave times and detailed safety information are published closer to the event and the organiser issues programme updates in the lead‑up to the race.
