The TUMMiler is one of the most scenic 100 mile runs in the world.

Starting at Te Puia in the heart of Rotorua, the 100 Mile course takes you on a journey across the most spectacular landscapes the region has to offer.

The highlights include running along eight different lakes, the solitude of the Tarawera Forest, a boat ride across Lake Rotomahana, the waterfalls on the Tarawera Falls track, twists and turns on the Eastern Okataina track, running through the archaeological site of Buried Village, the towering redwoods, steam alongside the trail at Sulphur Point and finishing at the Village Green in downtown Rotorua.

The terrain consists of mostly narrow single track trails, wide trails, forestry and sealed roads.

The TUMMiler takes a substantially different route to the TUM50 and TUM102 courses. The latter half of the TUMMiler course shares some trails in common with the TUM102 course.

Support Crew

Your support crew can be a big part of your day at Tarawera Ultramarathon by UTMB, and they're more than welcome to help get you through your Tarawera journey. Support crews can see you and assist you at specific aid stations, but may not assist you outside of these points. Assistance can include moral and verbal support, physical support, food and nutrition, hydration, and gear and equipment changes.

You should work with your support crew to formulate a detailed plan for them to assist you at various points on course. This includes estimating when you expect to arrive at supported aid stations, what support you might want at each, when they will need to meet you there and how they will get there.

The table below includes drive times between supported aid stations, as well as coordinates for each supported location to help with your planning.

Support crews, please note:

  • Support Crews can only assist their runners at the aid stations indicated with spectator access above. This includes 200m either side of the aid station on course. Outside of these areas support crews cannot provide material support (physical, nutritional, gear or otherwise) to runners on course. 
  • Please be courteous to other runners and support crews at aid stations.
  • If you intend to meet your support crew at an aid station, do not use the drop bag service for this aid station.
  • Support crews have just as long a day as the runner. Take the time and care to look after yourselves - plenty of food and water, dress for the conditions, and take the time to rest (sleep/naps encouraged) when you can between meeting points. 
  • Many roads that access aid stations are rural and narrow, windy roads. Please take care driving on these, particularly with increased traffic during the event.
  • The actions of the support crew are the responsibility of the runner. Any rules breached by crew will result in penalties or disqualification for the runner. 

Drop Bags

drop bag athlete content

drop bags right content

A drop bag service is available which allows you to have your own personal supplies (gels, food, change of socks, shoes, shorts, lubricant etc) available at certain aid stations.

At Athlete Check-in you will be supplied drop bag labels. Attach the corresponding bag label to your bag/s (see Aid Station table above for locations where drop bags are available) and drop your bag/s at the designated area at Athlete Check-in before 8pm on Friday. Your start line drop bag is dropped on race day at the start line info tent.

Please note:

  • Drop bags must not contain any glass
  • All liquids must be in secure containers
  • We cannot move bags between aid stations for you, i.e you must provide a bag for each location where you wish to have personal supplies.
  • Bags must be a soft and of reasonable size. Please don’t pack the kitchen sink!

If you have a drop bag at an Aid Station you will be asked to move it from the ‘unused pile’ to the ‘used pile’ even if you did not use your drop bag. This allows us to transport your drop bag/s quickly back to the finish line and will help allow the drop bag tent to remain orderly for the benefit of athletes yet to arrive.

You will receive one ‘Authority to Collect’ card at Athlete Check-in. This entitles your support crew to collect your drop bag/s from the finish line on your behalf. No one other than you (with your race bib as identification) or supporters with an ‘Authority to Collect’ card will be able to collect drop bag/s.

Please try not to use the drop bag service for any Aid Stations where your support crew will be attending.


Pacers are companion runners that can accompany a TUMMiler athlete from various points. Please check the Aid Station table above for the Pacer pick-up locations. Pacers run for free, but must be registered online no later than 11 February 2024. A link to register can be found on the athlete's registration confirmation email. The Pacer's role is to accompany their athlete, to provide moral support, pacing advice and companionship in the latter stages of the event.

There are strict rules regarding pacing:

  • Pacers MUST register themselves online as they will be required to sign a waiver.
  • All Pacers must wear a compulsory race bib number. Pacer(s) must attend Athlete Check-in to collect their bib.
  • The minimum age for Pacers is 18 years old.
  • Pacer numbers will be red and match the number of your athlete. This is so we know you are part of the event.
  • Pacers must carry their own set of mandatory clothing and equipment items to match that required by the TUMMiler athletes.
  • Pacers cannot meet their athlete before or after the designated start locations or at intermediate points. Doing so results in disqualification.
  • Competitors can use two Pacers – but only one at a time (they must change over at an Aid Station).
  • If you plan to make an exchange, you must hand over your pacer number to the next pacer.
  • Pacers are responsible for their own transport (though may wish to book the Okataina spectator bus - see here for details).
  • There are no Pacers for TUM21, TUM50 or TUM102 runners.
  • Pacers may not carry extra water, food or equipment for runners.
  • With the exception of an emergency or medical situation, Pacers cannot provide any material or physical assistance to their athletes.
