Yes, your MTB will be fine at the TUFF.

The Start/Finish will be on Canyon BLVD. next to the Village at Mammoth (6201 Minaret Rd, Mammoth Lakes, CA 93546). Underneath the gondola.

The short answer is NO. We recommend you register when you are confident you can make the travel but the event is only open to 1000 riders. If you know the history of getting this event off the ground, you know we have to protect ourselves to operate the event. Thanks for understanding. 

No. Thanks for understanding. 

Yes, you may transfer down to a shorter distance at no cost and you will not be refunded the difference. This can be done all the way until check-in on Friday as we'd rather you play it safer if you need to go shorter. You may transfer up to a longer distance and pay the additional cost for that category. This can only be done until online registration closes. 

We follow BikeReg policies:

-Can participants move into a less expensive category?

--Yes, but they will not be refunded for the difference in price.

-Can participants move into a more expensive category?

--Yes, they will be charged the difference and be prompted to checkout again.

Awards are given only to the TUFF-est (one person at the top in each category on all three courses). The ceremony will be saved for the morning after, on Sunday. We will gather to celebrate, tell stories, and do the raffle. 

Yes! We're bringing live music to 2023! You will receive a food and drink ticket with your registration. We will release information on where you can redeem this closer to the event.

YES! There will be enough neutral aid stations to get through both courses but you will be required to carry at least 3-5hrs of fuel at a time.

For the LONG COURSE, there are three aid stations. 

For the MEDIUM COURSE, there are two aid stations. 

For the SHORT COURSE, there is one aid station. 

There will be water and offered calories will be explained closer to event day.

For the LONG COURSE, they are not required but we will have space for them to meet you at the southern most part of the course. There will be an aid station at this location, so the support crews are not required.

For the SHORT & MEDIUM COURSE, support crews are not allowed for safety of the riders. It will also prepare riders to take on the long course in the future. 

It is recommended you carry a pack or some sort of bags on your frame, bars, etc. that allow you to carry a minimum of 2 Liters (67OZ) of fluids, 4hrs of nutrition, and extra clothing (you will be in the Owens Valley and temps can change quick).

YES! It's not called Mammoth TUFF for nothing. You are at altitude, riding in TUFF, and have a good amount of climbing throughout the day... If it was not TUFF we would not have used this as training grounds for two DK200 (Now - Unbound) wins and more.

The full courses will be announced the Monday before the event. There may be slight modifications from 2022. 

Yes. 

The TUFF Guide will have all the specifics of the event with all these questions answered.

As wide as your frame will allow!

38's will suffice, but we recommend 40 and above. Knobby tires that roll well are recommended.

Amanda's favorites are Rene Herse's 700x 42's and 48's.

The short answer is Yes! The TUFF Guide will have all the specifics of the schedule and time cutoffs.

We do have an E-bike category. E-Bikes will be allowed to ride on the short course only. If they are a category 1 - pedal assist and can hold a charge for 4 - 5 hours. There will be no prizes for this category as it is just one group.

If 2x we recommend something like a Shimano GRX crankset, or similar, with a 48/31 tooth chainrings and a 11-34 cassette.

If 1x we recommend a 40 tooth chainring with at least a 11-40 cassette but an 11-46 would be better.

*Note: We are saying a 1:1 ratio or easier. It is a long day at altitude.

Here is a good article on BikeRadar about Gravel Bike setups, focus on the Chainring, Cassette, and 1x or 2x sections.
