Race Date: July 26-27, 2019


Registration for the 2019 High Lonesome 100 is pretty straightforward. There’s no lottery or complicated entry system. It’s a first-come-first-serve process who’s only requirement is that you meet the qualification standards (see below) before you register. Due to the demand and our cap of 125 runners, the race fills up in a few hours. We do go through the waitlist, so don’t be shy about getting onto the list if you are late to registration. Full details are available below, best to read them all carefully.



Registration for the 2019 High Lonesome 100 opens on November 1st, at 1:00am Mountain Standard Time. We use UltraSignup as the registration platform, and there are numerous questions at the time of registration. Please answer these questions accurately as we do verify them. The entry fee is $375 regardless of when you sign up.

Registration for 2020 is currently planned for November 2nd, 2019 at 1am MDT, BUT WE MAY BE DOING A LOTTERY…TBD. The 2019 event sold out in 9 minutes.


The High Lonesome 100 is not an easy race. It's high, remote, rugged, relentless, and steep. This race will test even experienced endurance runners who have run mountainous 100 mile races. We have these qualification requirements because we believe that to have the best chances of succeeding, you need to have some experience with long distance or 100 mile trail races. You cannot register for the race without having completed a qualifier. In order to enter to run the High Lonesome 100 in the given year, you must meet one of the following requirements:

2019 High Lonesome 100:
- Finish a 50 mile or 100k trail race between Nov 1st, 2017 and October 31st, 2018. 
- Finish a 100+ mile trail race within the past 10 years

2020 High Lonesome 100:
- Finish a 50 mile or 100k trail race between Nov 1st, 2018 and October 31st, 2019. 
- Finish a 100+ mile trail race within the past 5 years

2021 High Lonesome 100:
- TBD pending review of 2019 results. A lottery is possible, but we’d like to avoid it. Expect tighter requirements this year…meaning a 50 miler/100k may not work as a qualifier. 

Tiny details:
1. You must wait to register until you are qualified meaning you cannot enter the race or waitlist until you have completed a qualifying race. The RD may, at his discretion, waive this requirement.
2. A trail race is defined as any race that takes place at least 75% on non-paved surfaces. Non-paved surfaces include singletrack, double track, mining or logging roads, gravel roads, or dirt roads.
3. Finish is defined as an official finish as classified by the respective race.
4. High Lonesome 100 runners who DNF may use the High Lonesome 100 as a qualifier provided they at least get to Hancock (mile 50) prior to cut offs. This qualification is only good for one year, so if you drop in 2019 it will only get you into 2020. Dropping prior to Hancock does not count as a qualifier and you will need to ensure you have another qualifier should you wish to sign up.




The 2019 High Lonesome will not offer any refunds or deferments, with the following exceptions:

1. Deferral is allowed to registered entrants who have been selected to run the 2019 Western States Endurance Run or the 2019 Hardrock 100. This does NOT include being selected to the respective waitlists. The deferral amount allowed is 75% of the entry fee (not including fees, trail work opt outs, additional purchases, or miles-to-dollars donations). Deadline for requesting the deferral is 12/31/18. You must still meet all qualification requirements to run the following year.

2. A full refund is allowed for female entrants who become pregnant after registering for the race and no longer wish or are able to run in the 2019 event. Non refundable items are fees, trail work opt outs, additional purchases, or miles-to-dollars donations. Deadline for requesting the refund is 6/1/19.


Find yourself on the waitlist? Don't fear, we've gone through the list in both previous years. In 2017 we had 73 out of 75 spots filled come race day, and in 2018 we had 100 out of 100 filled. Our anticipated turnover for 2019 is between 15-30%, and each spot typically takes 2 waitlisters to fill...meaning that if we have 15 people drop, it would likely take 30 waitlist spots to fill those. If we have 30 people drop, it would take 60 waitlist spots to fill those. So, even if you are somewhere in the 30-60 position on the list, there is still a very good chance you will get in. Every year we have had a couple spots open up the week of the race, so if you are the last minute type there is usually a chance you can get in. 

If you are on the waitlist, you must still meet all the qualifying and trail work requirements. If you have completed your trail work prior to the trail work deadline, you will be moved to the front of the line once the deadline has passed. 

Please note, Ultrasignup does not charge you when you register for the waitlist. You get charged only if you get an invitation AND accept it. If you decline the invitation, you get removed from the list. When an available spot opens up, you will receive an invitation from UltraSignup and an email from the RD. You have 48 hours to accept the invitation before the spot is passed to the next person on the list. If you miss the invite, you have to start from the back of the list.

Questions? Email the RD, but also be patient. Most of the waitlist action happens from March-July.
