C. B. from Missouri (6/7/2023) "Great Wyoming Race" (about: 2023) 11-50 previous marathons \| 1 Casper Wyoming Marathon COURSE: 4 ORGANIZATION: 5 FANS: 2 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.
J. J. from Wisconsin (6/17/2021) "Great race with a wonderful RD" (about: 2021) 50+ previous marathons \| 2 Casper Wyoming Marathons COURSE: 4 ORGANIZATION: 5 FANS: 2 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!
Diana Rosenal from Cincinnati, OH (6/9/2021) "The Marathon to run in Wyoming" (about: 2021) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 4 ORGANIZATION: 5 FANS: 5 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!
RAEF S GUIRGES from TORRANCE, CA. (6/3/2019) "I ran 184th. FULL MARATHONS including CASPER" (about: 2019) 50+ previous marathons COURSE: 5 ORGANIZATION: 4 FANS: 3 I finished a marathon in each states once and I have 3 states left for my second round. I loved the service station during the entire course, with over 80 F and high humidity, they served cold drinks, watermelon, orange, power drinks and also during the entire 26.2 miles there was a lot of marathon organizers riding their bikes to make sure that all runners are safe during an abnormal weather. For next year recommendation, more clear signs need to be displayed. Thanks.
M. E. from NY (6/19/2018) "Wish the Course was Marked Better" (about: 2018) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 1 ORGANIZATION: 1 FANS: 1 I agree with what others had said. Everything was fine with this race until it wasn't (which was around mile 10.5). There needed to be more markings or signage or people directing you on critical turns on this race. The golf course loop was a mess. Then when you got to the trail there were splits and forks with no directions. I stopped at mile 17.5 or so with not a person in sight wondering if I was on the course. I was so stressed out about getting lost. This was my 121st full marathon, and I have never gotten loss or seen such a poorly marked course. I was relieved to have finished even though I ran an extra half a mile. I heard other runners who had run an extra 1 mile.
K. A. from MA (6/12/2018) "Hot and dry" (about: 2017) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 2 ORGANIZATION: 4 FANS: 2 I had high hopes for this race particularly when I heard this was a new course. If this was an improvement I'm glad I did not run the old one. Wyoming is the 10th largest State, why would you have to run two loops within this course? Not enough land? Apparently while the race director was speaking at the pasta dinner lauding her staff on the great job they did, and honestly all those people did a wonderful job and should be congratulated. The number pickup was excellent, the dinner was superb, the organization and friendliness was top notch. But somebody was supposed to mark the course and was a no show. So they say. I had a runner ahead of me stop and come back and ask me if she was going the right way. How do I know - I'm following you. There was a true Wizard of Oz moment after mile 18 with a fork in the rail trail. I had no idea what to do - some people like to go this way, It's pleasant down that way too. Of course people do go both ways. The only thing missing was the scarecrow. So I waited until another runner coming back said they meet back together in a tenth of a mile, it doesn't matter. How am I supposed to know that?! And the golf course loop - don't get me started there. For ten miles I was consumed with the anger and frustration of possibly being lost and wanting to buy the race director a can of spray paint. I don't know what got me more, the altitude, my attitude, the sun, the temps or the dry air but it wasn't a fun day for me. Somebody in Wyoming needs to create a race that buses you up a mountain 26 miles away and you run down to the finish, no confusing rail trails, no up and over bridges crossing the river (you'll know what I mean if you run Casper, that got old as well). Just an easy course where you know where you're going, out of the sun, some time of year when it is cool out. And maybe you'll see an antelope. As for this race if they put volunteers at turns, roadside signs along the way, and paint a logo and arrow at turns (and potentially turns, but not turns you should take) and knock off the loops, I'd recommend you run this. But I'd want assurances before I signed up.
H. B. from Calgary Alberta (6/10/2018) "Everything good except the course" (about: 2018) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 1 ORGANIZATION: 4 FANS: 3 What were they thinking when they put this course together.Twist turns double loops no timing mat.Volunteers bunched together and zero at critical forks in road.But everything else was good.Especially the after race festival and food.
P. O. from Holland, Michigan (6/10/2018) "Small race with a big heart." (about: 2018) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 3 ORGANIZATION: 4 FANS: 2 Kudos to race director Marlene, and race manager Nicole for helping me to get credit for running the Casper marathon. The course had many twists, turns and switchbacks, way too many I'd say, and not well directed by volunteers at the various course change points. I missed a section and finished the race too soon but was allowed to (and shuttled to) return to the missed section to complete the race. I came away from the Casper experience with a profound regard for the Casper community that to a person seemed kind and friendly. The pasta dinner offered a great presentation by George Rehmet, Western Region Director for the RRCA, and great food. The organization start and finish food was more plentiful and varied than I had ever seen. Thank you to Casper for making a very small marathon a very worthwhile one to participate in.
J. E. from Columbus, Ohio (6/7/2018) "Poorly marked course causes significant issues" (about: 2018) 11-50 previous marathons \| 1 Casper Wyoming Marathon COURSE: 1 ORGANIZATION: 3 FANS: 2 As others have said, small town marathon, new race director, sounded like a new course for 2018. Slightly hilly and high elevation gives you a challenge but the early start helps keep things cool. Pros: Aid stations were frequent and well stocked. Start and finish areas were well done. Cons: No timing mats Course poorly or just not marked in many areas. We ran an extra .5 miles around the golf course (someone below said we missed the inner loop). I remember that fork well and the volunteer had everyone going the same way. Most of the course was not marked and you could have easily took a wrong turn if you didn't trust the person ahead of you (or if you were running alone). However on the way back on the out and back I did see arrows freshly put down but too little too late. Hopefully they fix this for next year or change the course so it's not so complicated. Unfortunately not much choice to run WY but it's not a terrible race.
A. N. from Rockville, MD USA (6/4/2018) "Big Al's Comments" (about: 2018) 50+ previous marathons \| 1 Casper Wyoming Marathon COURSE: 3 ORGANIZATION: 4 FANS: 1 This was a new course and a brand new race director. She had done a decent job of organizing this race. The expo was small with only a few local vendors. The pasta dinner was also worth the $15. The marathon only had about 120 runners, which made you run by yourself the majority of the time. The race started at around 47 degrees and very sunny and at about 5,100' of elevation which made it hard to breathe, especially if you're running hard. The first 5 miles are a loop with a long and challenging hill, followed by a steep descent. The rest of the course was along the Platte River Trails, with the exception of a few blocks in downtown Casper. Around mile 11, we did 1.5 loops around a golf course. Be careful, since the first time you come to the golf course, you're supposed to take the inner loop and the second time on the outer loop, which the volunteer failed to advise the runners on, even though the course was marked!! As a result, most of us ran an extra 0.5 miles!! There are two back to back hills at around mile 19 that are nearly impossible to run, but luckily they're short. The last 6 miles are towards the finish line and on the same path. The actual finish line is very small and not too festive. The volunteers did a great job and there was plenty of GU, fruits and fluids on the course, but nearly zero spectators. The temperature at the finish line was around 70 degrees, so overall, a somewhat pleasant day for an endurance race, especially knowing it could be in the 80s here very easily. If you need Wyoming for your 50 states or you're looking for a very small and low key race, this is the one, otherwise you can skip it.
