Mauna to Mauna Ultra


Mauna to Mauna Ultra Cancelled

We have decided to cancel M2M 2023 and have no future plans to bring the race back.



We have received glowing testimonials from hundreds of competitors from over 50 countries across the world.  Here are just a few:

It is truly remarkable what we can accomplish when surrounded by top notch race directors, volunteers, medics, and competitors in the most beautiful, hardcore, relentless terrain. The Grand to a Grand attracts the best of the best. Everyone pours their heart and soul into this event which makes it one of a kind.
Attention to detail, extremely well organized, and support unlike anything I have ever seen. Thank you all for the adventure of a lifetime...I am so happy and proud to be a part of the Grand to Grand family. Just sign up! – Alison L’Heureux, USA - G2G 2017

An absolutely fantastic event that stands head and shoulders above almost anything else out there. Very physically demanding with some highly technical pieces, unrivaled ever changing scenery, simply the best race crew/volunteers and medical team I have come across anywhere in the world with relentless passion and support who I believe are the heart and soul of the event and the most inspiring group of runners I have had the pleasure of running with. – Anthony Ward, UK - G2G 2017

If you are thinking of your first multi stage ultra then look no further! If you want to be part of a family rather than just a number, this is the race for you! It is without a doubt the greatest experience I have had so far. The course is demanding yet spectacular, the views are incredible. The support team are amazing..ALL the crew, from the tents being set up, the organisation of the checkpoints, the medics treating the worst feet imaginable it is first class! Finally, the other competitors are the icing on the cake, you meet some remarkable people from around the world that keep you going until that final mountain climb. Thank you, Tess and Colin you have created a fantastic ultra-experience……..did I mention there is SAND….and lots of it – Aaron Oliver, UK - G2G 2017

Grand to Grand was my 4th staged ultra and the only race I went back to do a second time. It was that good. Professional race production by Tess and Colin Geddes, who are real people and not a big greedy company. Both racers that care about racers. Once you finish you are part of the family. Trust me. – Christopher Ballou, USA - G2G 2014 and 2016

An incredible adventure that is so much more than a stage race. Seeing a unique part of the world, pushing yourself beyond what you think you're capable of, making lifelong friends and feeling part of the G2G family forever. One of the best experiences of my life. Just do it, you won't regret it. – Philippa Hammond, UK - G2G 2016

A fantastic event run by fantastic people! Go stretch your boundaries, go far beyond your comfort zone, and discover that the limits you thought were there are not. Walk, run, shuffle, or crawl, this race is worth doing in so many ways. - Peter Opdahl, USA - G2G 2016

So much fun. Well organised and you will make friends for life from the people you meet at these events. Check out the M2M as well. Thanks Tess and Colin! – Kylie Williams, Australia - G2G 2015

This was my first ultra and was wondering what to expect. Turned to be one of the best sport / human event I've done – Yannick Debaupte, France - G2G 2017

The best organized event I have attended since the Olympics. WoW!  
-  Dave McMahon, Canada - G2G 2012

The event was unbelievably fantastic. This must be the best self-supported ultra in the world today!
-  Jo Petersen, New Zealand - G2G 2012 and 2013

G2G marked three things off my bucket list: stage race, Grand Canyon, slot canyons!
- Elizabeth Hamrick, USA - G2G 2013

G2G was nothing less than the coolest thing I've ever done. A life-changing experience.
- Becky Le Baron, USA - G2G 2013

The Grand to Grand was without a doubt the most challenging, beautiful, and rewarding experience of my life. I made lifelong friends and have been forever changed by having participated.
-  Julie White, USA‬ - G2G 2013

I attempted this in 2016, didn't make it all the way but even so it is a memory I will keep forever, can't wait to go back and try again, highly recommend and can't say enough good things about the people that volunteer and organize this.  - Joel Koscielski, USA - G2G 2016

Thanks Tess and Colin and all the other organisers/advisors of the G2G race for organising such an amazing event!!! Everything was perfect, the course, the campsites (incl real toilets every time!), the welcome cheers when arriving at a checkpoint/finish! Loved it all! Big kiss!
–  Astrid Valks, Netherlands - G2G 2012

Grand to Grand is the most intense, surprising, intimate and exciting emotional experience and extremely challenging, brutal and satisfying physical experience any human or athlete can experience. The relationships and bonds formed during G2G are indescribable and so incredibly fulfilling.
-  Telma Altoon, Armenia - G2G 2014

For anyone who enjoys facing a huge physical and mental challenge amid some of the most stunningly beautiful panoramas in the world, the G2G Ultra is perfect for you.  Very well organized, wonderful people in the race and volunteering, all make for a tough but never-to-be-forgotten event.  I had a blast!
-  Gregory Castle, USA - G2G 2014

From the moment I arrived I was made to feel very welcome. Very well organised, all the Volunteer's / Medical staff always had a smile on there face when you reached a check point and where there to help you if you needed it. I feel they went above and beyond and gave it that personal touch that made it one big Family, one which I will never forget. I cannot recommend this event highly enough to anyone who is thinking about it sign up you wont forget it. – Ian Dalton, UK - G2G 2017

I join many races but have never had this sweet feeling before.
I enjoyed G2G so much - it was a lovely run.
The staff is perfectly organized, the medical team is very professional and the volunteers are very passionate.
This is definitely the best ultra marathon race.
- Tommy Chen, Taiwan, Winner of the G2G Ultra 2015

I am in awe of your organisation, I feel so privileged to have run in such an area and it will be a hard one to match anywhere in the world. Thank you so much for giving us all such an amazing experience, it will rank up there with one of my favourite races. An unforgettable experience. A week I will remember fondly for many years to come.
–  Sharon Gayter, UK, world record holder and first female at G2G 2012

G2G.....WOW ...epic, challenging and breathtaking....We all started out as strangers and ended the week as one big family. How lucky I have been to experience such an incredible event. I went away feeling like I had discovered just a bit more about myself and truly believe when you think you can't you really can..... Just Dream Big. Thank you everyone for making the week so special.
- Sandy Suckling, Australia - First Female, G2G 2015

I don’t know how many races I've done in my life, but I assure you that there have been many. I’ve met many organizations and many runners. But this has been one of the best organizations I've ever met. My sincere congratulations to the organization and all runners who made it possible for me to spend a few days in a place as wonderful and spectacular.
–  Salvador Calvo Redondo, Spain, winner of 23 ultra marathons worldwide and first winner of the G2G Ultra - 2012

When you find yourself in a far off place and it causes you to re-think some things, you start to think that slowly you are becoming someone else. You will make the most amazing new friends and you start to think the things that have been lost on you are now as clear as a bell.‬ ‪If you are going through life so sure of where you are heading and you wind up lost, it’s the best thing that will ever happen to you.‬ You will laugh, you will cry, you will be knocked down and you will get up again.‬ You will wonder what the hell you are doing here, but nothing can ever compare to the elation of crossing that finish line.‬ ‪If you want to find a new you then get on that start line. What’s the worst that can happen. ‬ Oh and by the way, easy it ain’t.
