Race Registration

The fields for the 2023 In-Person 10 Mile, and for those wishing to do the “Double Blossom” (run the 5K on Saturday, April 1 and the 10 Mile on Sunday, April 2), will be determined by Lottery. The lottery will be held from December 1 – December 15. Lottery results will be posted by December 19. Note that this year there will not be a lottery for those who wish to run only the 5K – registration for the 5K will open on December 20 and will stay open on a first-come, first-served basis until February 28, 2023, or until the field limit of 5,000 is reached, whichever comes first. Click Here for full details on the 5K, scheduled for Saturday, April 1. Registration for the 2022 Virtual Run will open on January 2, 2023, and close on April 10, 2023.

Entry Fees

The entry fees for the 2023 In-Person 10 Mile Run is $55. The entry fee for the 5K is $45. The entry fee for the 2023 Virtual Run is $40 whether you choose to run the 10 Mile or the 5K.

Switching to the 5K

We understand that sometimes injury or time pressures can sideline your training for a 10 Mile race. If your training doesn’t go as planned, you will be able to change from the 10 Mile race to the 5K race, as long as the entry limit of 5,000 registrants for the 5K has not been reached. The cutoff date for any race switches is Sunday, March 26; there will be a $10 fee for race switches after February 28.

After the 10 Mile Lottery is over, if you have been accepted into the 10 Mile but want to switch to the 5K, we will post a form here for you to use to change your registration.

If we have not reached the 5,000 runner entry limit for the 5K and you fill out the form by February 28, there will be no fee for the change. Your registration information and name will be pre-printed on your 5K bib number, which you can pick up at the Expo on Friday, March 31 from 3:00 P.M. – 7:45 P.M., or at the race site on Saturday April 1 starting at 7:00 A.M. You will receive a 5K t-shirt, and if you purchased a 10 Mile medal, you will get a 5K medal when you finish the race.

If we have not reached the 5,000 runner entry limit for the 5K and you fill out the form after February 28, there will be a $10 switch fee. Your registration information will appear on your 5K bib, but your name will not. You can pick up your 5K bib number at the Expo on Friday, March 31 from 3:00 P.M. – 7:45 P.M., or at the race site on Saturday April 1 starting at 7:00 A.M. You will receive a 5K t-shirt at packet pickup as long as we still have one in your size. If you purchased a medal when you registered for the 10 Mile, you will receive a 5K medal as long as we still have medals in stock.

No race switches will be allowed after Sunday March 26! You must wear a 5K bib to be allowed to run in the 5K. Anyone who runs the 5K race with a 10 Mile bib, or the 10 Mile race with a 5K bib, will be disqualified from both races.

Wave Start

The Ten Mile will use a wave start again this year. Runners will be assigned to a color-coded starting corral based on previous race times. Colors on bib numbers will match starting corrals. There will be five waves of approximately 3,500 runners each. The waves will start in 3-5 minute intervals. Runners outside the top 25 males and females will be scored on net times.

Seeding Times Required

In order to ensure a safe start in the 10 Mile, we will be lining up runners into six corrals based on previous race times. All entrants must provide a past 10-mile time (or a projected time based on a 10K time). If you have run the race in the last three years, we reserve the right to seed you based on the time(s) we have on file. Individuals not submitting a time will be placed in the slowest time group.

Stroller Policy

No strollers are allowed in the 10 mile run. Push-assist pairs (“duos”) are categorized as wheelchairs and are permitted in the 10 mile run.

Wearing the MyLaps Bib Tag

Runners will be timed and scored using the MyLaps Bib Tag. There is a single Bib Tag adhered on the back of your bib number. Simply leave the Bib Tag where you find it — on the back of the bib. Do not remove it. The Bib Tags are single-use.

Time Limit

Due to National Park Service restrictions, we can only keep the 10 Mile course open for a maximum of 2 hours and 20 minutes after the 7:30 A.M. start, so everyone must be able to complete their race in 2:20:00. No runner who takes longer than 2:20:00 to finish the race from the time they cross the starting line will be given an official finishing time. This is true regardless of the corral in which you start the race. So if you start in the Green corral at 7:45 but it takes you another minute to actually cross the start line, then you would have until 10:06 A.M. to finish the race and be scored. If you are in the Red corral, which starts at 7:32, but it takes you a minute to cross the starting line, then you have until 9:53 A.M. to finish the race. If you don’t beat the time limit in that case, you will be able to finish the race since the finish line won’t be closed, but you won’t get an official finishing time. As a result, all we can post is the time the finish line will be closed (10:20 A.M.) – it doesn’t mean everyone who finishes before that time will be scored. This means that trying to jump into a faster corral that starts earlier won’t make your finish time limit any longer.

Remember, if you are concerned about the 2:20:00 finish time limit, you should consider switching to the 5K and enjoying a less stressful run or walk. Switching will be permitted up until March 26 as long as the 5,000 runner entry limit has not been reached, though there will be a change fee of $10 for any switches made after February 28. The 5K finish time limit is 1:05:00 (21:55 pace per mile).
