The Tarawera Ultramarathon 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.

Tarawera Ultramarathon by UTMB route
The Tarawera Ultramarathon by UTMB has four races; the TUM21, Bachcare TUM50, TUM102, and the TUMMiler.
The TUMMiler is the Tarawera Ultramarathon by UTMB’s flagship 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 TUM102 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 TUMMiler route North-East of Mount Tarawera, which they will then follow to the finish in Rotorua.
The Bachcare TUM50 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 TUM21 is a 21km race with 734m of elevation. Starting with a loop around Lake Tikitapu, runners will then race to the finish in Rotorua.

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