Martini Marathon (Baanmarathon)

The Martini Marathon is a full marathon run entirely on the athletics track in Stadspark, Groningen, typically on the fourth Friday of September. It occurs biennially, with participants selecting either the solo marathon or a relay format. The race is straightforward and distinctive: rather than a road loop through the city, the entire marathon is completed on the track. Relay teams consist of three to five runners, while solo runners complete the full distance individually. All participants operate within a five-hour time limit.
