The Tarawera Ultra-Trail by UTMB is a collection of UTMB World Series trail running races in New Zealand.
Held in February of each year, the race is based in the town of Rotorua on New Zealand’s North Island, with the inaugural edition held in 2009.
In 2021, the event joined the UTMB World Series meaning it began to offer running stones to competitors in all four of its races, allowing them the chance to qualify for the UTMB World Series Finals at the Ultra Trail du Mont-Blanc.
Date, start time and live tracking
The Tarawera Ultra-Trail by UTMB traditionally takes place in February, with the 2025 edition taking place on February 15-16, making it the second race in the 2025 UTMB World Series.

The event will welcome more than 4,000 athletes across one of four distances – 21km, 50km, 102km and 100 miles (165km).
And the 102km race is once again a HOKA Golden Ticket qualifier (2 M/F) for the 2025 Western States and has attracted an exciting line up of elites from around the world for the event’s hero race – more details here.
Tarawera Ultra-Trail begins at 4:00am local time on Saturday 15 February for those taking part in the 100-mile race, with athletes given a total allowable time of 36 hours to complete the course. All other distances also start on Saturday, with the 50km and 102km races underway at 7:00am and the 21km at 10.00am.
Live tracking is available on the UTMB Live website here.
Tarawera Ultra-Trail by UTMB route
The Tarawera Ultramarathon by UTMB has four races; the T21, the T50, T102, and the TMiler.
The TMiler is the Tarawera Ultramarathon by UTMB’s 100 Mile race. Starting at Te Puia in Rotorua, it takes runners throughout the geothermal surroundings of the region, with competitors crossing eight different lakes (which includes crossing Lake Rotomahana by boat), running along single-track paths surrounded by Redwoods and navigating around Mount Tarawera before returning to Rotorua at the Lakefront Reserve. It has a total elevation of 5470m.
The 102km race starts in an entirely different location, at Firmin Field in Kawerau – an hour east of Rotorua. From there runners must tackle 3089m of elevation as they first travel southwards to join the TMiler route North-East of Mount Tarawera, which they will then follow to the finish in Rotorua.
The T50 takes runners on a shorter journey around Rotorua, leaving Te Puia and taking runners southwards to Lake Rotokakahi and Lake Tikitapu before finishing in Rotorua once more. It has a total elevation of 1572m.
Finally, the point-to-point T21 is a 21km race with 734m of elevation. Starting with a loop around Lake Tikitapu, runners will then race to the finish in Rotorua.
Facts, tips and FAQ

Tarawera Ultra-Trail by UTMB records and past winners
Whilst it only joined the UTMB World Series ahead of its postponed 2022 edition, Tarawera Ultra-Trail by UTMB has taken place in some form annually since 2009.
In 2009 the longest race was 85km, and the 100-mile TMiler was not introduced until 2018. In 2014, Cyclone Lusi meant there was an altered long (73km) and short (63km) course.
