Backyard Laramie

What is a backyard ultra?

A backyard ultra is a race format, invented by the (in)famous Lazarus Lake, in which runners must repetitively complete a 4.17 mile loop every hour on the hour (one completion = one "yard"). This means if you finish your loop in 40 minutes---great!---you have 20 minutes to rest until your next loop. The race is over when only one runner remains to complete a lap. Backyard ultras are great in that anyone who can run 4.17 miles can compete! Fast or slow, 2 laps, or 24 laps, the hour-by-hour format encourages participation by all. Official rules can be found here.

What is the course?

The course can be viewed here. The route is entirely on a gravel path. There is around 220ft of elevation gain, and it is a few hundredths of a mile longer than the traditional backyard length. Boohoo! That's how it goes in Wyoming.

What do I need to know?

• There will be some food and water provided, but it is good to bring enough to sustain yourself for however many laps you expect to do.
• We recommend bringing a chair to sit in between laps (we'll have a tent for the aid station).
• If you want to run into the night, you are required to have a headlamp with extra batteries.
• Runners also need to have a phone or a way to contact the race director in the event of an injury.
• Weather this time of year in Wyoming is unpredictable. We encourage you to prepare for all possible elements, including snow, rain, wind, and the sun, and it may be a good idea to bring multiple pairs of socks and shoes.
• Parking is free and normally plentifully available along Willett Drive.

How do I sign up?

Sign up here, on UltraSignup, before the April 16, 11:59PM deadline! Again, registration is FREE, but please consider making a donation to the Trail Fairies (you'll have the option when you register!).
