Casper Marathon 2025

This is a small, but well-run race. Would highly recommend if you're looking to check Wyoming off your list. The course starts with a 4 mile loop in the rolling hills north of town before a huge downhill at mile 6. The remainder of the race is an out-and-back along a river trail (with a loop downtown and around a golf course). There are some notable hills at mile 15/23 and between 18-20, but nothing too severe. It's not a flat course, but I wouldn't call it difficult either. Organization was top notch. Having the Event Center open prior to the start made waiting so much easier (plenty of pre-race bathrooms). Aid stations were plentiful and the course was well marked. Finish line was well-stocked with food and drinks. Several hotels around the finish area plus there was a shuttle to the start line. Fan support was pretty sparse, but that's to be expected with a small race in a smaller city. I personally didn't feel the effects of the elevation (Casper sits at about 5100 feet), but I did speak to a few runners that noticed it.

Do Casper. It's a challenging course but fair. RD is wonderful--quick to respond to emails and put together a great race experience. Be prepared for wind and a few hills, and don't discount the elevation. I will be back!

I ran the 2021 full marathon and have only glowing reviews for the race director, all staff and volunteers! In looking at the marathon course, it appears to have a lot fewer aid stations than it actually does have. The aid stations were frequent and well stocked with water, Gatorade, ice, potato chips, watermelon as well as first aid items. The volunteers at the aid stations and finish were very knowledgeable about the impacts of altitude and heat for running and were very well equipped to provide what was needed to ensure success for the runners. I had a particularly difficult time with the heat and altitude and was checked on regularly by a gentleman in a four-wheeler. He ensured I was OK to continue and provided ice and water, which made a huge difference. Without this along with the quality of the aid stations, completing the marathon would not have been possible. I am extremely grateful to all involved in putting this top notch event together. A couple other very important notes: 1) The reviews from earlier years related to the course not being marked is no longer a concern. The course was extremely well marked along with individuals at specific points to ensure the runners knew where to go. Frankly, the course was so well marked, I was never confused about how to stay on the course. 2) The staff, volunteers and other runners were extremely supportive and friendly at the start, packet pickup, aid stations, throughout the race and the finish. 3) My sister ran the half and we decided to fly into Denver and drive to Casper. We were happy with and recommend this approach as we found Wyoming terrain to be very unique. 4) My rating of the course of '4' instead of '5' had to do with altitude and heat. This was a successful marathon experience for me and I recommend Casper Marathon as the Wyoming marathon of choice!
