Race Registration

In-Person Ten Mile Run and 5K Run-Walk. The field will be filled slightly differently this year, as when the race was cancelled in 2020, 12,000 registered runners opted to defer their entry and get a Guaranteed Entry in 2021 rather than taking a refund. These runners will receive a Guaranteed Entry Link that will enable them to register for this year’s race starting on May 26, 2021.

The rest of the field will be filled by Lottery. The lottery will open on June 1, 2021 and run through 11:59 PM on June 30. Click Here for full details on the lottery, and for other methods of entering the race.

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 six waves of approximately 2,500 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 the large number of tourists in town for the cherry blossoms, we can only keep the course open for a maximum of 2 hours and 20 minutes after the 7:30 A.M. start. If you cannot complete the course in under this time limit, switch to the 5K Run-Walk instead.
