S. W. from Boise, ID (6/19/2015) "A pleasant surprise!" (about: 2015) 6-10 previous marathons \| 1 Teton DAM Marathon COURSE: 5 ORGANIZATION: 5 FANS: 4 I LOVED this race! I was pretty nervous about the field being so small (less than 100 marathoners finished), but the organization and enthusiastic volunteers made me feel like it was a marathon just for me. I got tons of cheers and high fives and even a hug just for me. Because there were so few of us and we were spread out, the volunteers, spectators and relay team members would cheer for you when you came by (rather than the spectator fatigue that comes with a steady stream of runners). The Teton dam start was perfect. It was beautiful and you didn't have to wait long for the 6:30am start. It was very informal with the RD just calling 'go.' The weather really cooperated that morning with just a little wind as it started to get warmer which was perfect. There isn't much traffic at all, so I was really able to enjoy the scenery. There is a portion of a few miles near the beginning on dirt road, which could perhaps be less enjoyable (muddy) in a heavy rain. I thought the course was beautiful and I even really liked the hills at the end for a change of pace. I even got my 2nd best time. The medal was great and the finish was fine. (I kind of wish there were different medals for the marathoners vs. relay runners and I would have loved to be able to purchase a hat for the race, but none available other than as awards.) The dinner/info meeting the night before was nice too. I would definitely recommend this one!
M. A. from IL (6/15/2015) "Peaceful" (about: 2015) 11-50 previous marathons \| 1 Teton DAM Marathon COURSE: 3 ORGANIZATION: 5 FANS: 4 I signed up for this race because it worked out logically in my quest for 50 states. This was the weekend after the Deadwood Mickelson marathon in SD, and we spent the week in between on vacation in Yellowstone and the Tetons. I really liked this race. It is a point to point rural course with few runners and a nice early start. Add beautiful weather, exuberant volunteers, and a supportive small community, and you have a fabulous race. I know there are a lot of great marathons in Idaho, but Teton Dam should not be overlooked.
J. L. from Idaho (6/16/2014) "Small town race, big time challenge, lovely area" (about: 2014) 11-50 previous marathons \| 6+ Teton DAM Marathons COURSE: 4 ORGANIZATION: 4 FANS: 4 I'm a local so I've run this marathon 7 times, and 2014 was by far the best year yet. They have really made some improvements: cash awards, good-looking, high-quality medals with the year on them (not the generic, reusable type like they had before), 'king of the hill' challenge which gave a cash award for the fastest split time up the hill at mile 19, good food and free massages at the finish, chartered busses to the start line (much more comfy than school busses), nice tech-shirt, functional sports bag, and stainless steel thermos bottles for age group winners. The winning time for the men's marathon was only 3:13, and the guy got $400 bucks! They must have given out close to $2000 total in prize money and raffled off several pairs of shoes, $50 gift cards, etc. I think they must have had a new race director because this was a total turnaround from 2012 when I ran it last. There are still a few improvements they could make (for example, why isnt there an elevation profile of the race on their website?), but combine it with a weekend in the Tetons or Yellowstone and this makes for a fun trip. Do some hill training before you come. Mile 1-18 is mostly flat, but 18-23 is a challenging gradual climb, followed by a few rolling hills from 23-25, and mile 26 is all downhill.
B. P. from Bountiful Utah (6/16/2014) "Very good out in the farmland course." (about: 2014) 50+ previous marathons \| 3 Teton DAM Marathons COURSE: 4 ORGANIZATION: 5 FANS: 2 Good but tough course. Very good support along the course. Nice finishers metal. Very good dinner the night before.
S. N. from Annapolis, MD (2/14/2012) "Dont count on gettng your medal" (about: 2011) 50+ previous marathons \| 1 Teton DAM Marathon COURSE: 3 ORGANIZATION: 1 FANS: 1 As a member of the 50 state club, i was anxious to run Idaho and collect my medal to commerate the event. I finished mid pack in around 4 1/2 hours and was told they ran out of medals because they handed them out to the relay runners. They told me not to worry as they wrote down my bib number and they would mail it to me when they had more. Well, no medal has showed up. I emailed the director 3 times to no response. Finally i received a response from someone else when they emailed me to sign up for this years event. They apologized and promised to mail my medal the very next day. Well, 2 more months have passed and no medal has arrived. My 50 state collection will have a hole where Idaho is suppose to go. So run Boise, or run somewhere where they deliver what they promise!
Marty Cooke from Pocatello, ID (9/28/2011) "register early" (about: 2011) 3 previous marathons \| 1 Teton DAM Marathon COURSE: 3 ORGANIZATION: 2 FANS: 4 Make sure you register early or you will be cheated out of the shirt that you pay for. I registered 4 days prior to the event and was told 'Since you registered late, you'll have to get your shirt later.' I was told I would be emailed about getting it (never happened) and that a shirt had been mailed to me (twice). Never got the shirt and the director has quit responding to my inquires. Won't run this again. I hate to get cheated out of what I paid for.
J. L. from Billings, MT (9/10/2011) "Okay race, disorganized finish" (about: 2011) 2 previous marathons COURSE: 2 ORGANIZATION: 2 FANS: 2 When I picked up my packet the night before I was told I would get my shirt the next day. However, at the end of the race everything was in short supply. No more shirts, no more medals, very little food. An overwhelmed race director was taking names and email addresses from disappointed runners promising to send medals and shirts. I emailed the race 3 times providing my name and address asking to please at least to be sent a medal. It is now 3 months later and I still have not received any response. I'm not very pleased by the lack of response. Community support is low, but volunteers were enthusiastic. As for the course, I'll say that after seeing 20 miles of potato fields, the last 6 miles of potato fields made me feel like I was running in place. And the last 9 miles felt like they were all uphill. So, mediocre course, bad ending, nice volunteers.
Marty Cooke from Pocatello, Idaho (8/2/2011) "Make sure to register early." (about: 2011) 1 previous marathon \| 1 Teton DAM Marathon COURSE: 4 ORGANIZATION: 4 FANS: 2 Great and wonderful marathon. The sponsor of the marathon was very active and seen throughout the race cheering and encouraging. Poor community turnout or support. My only complaint would be that when I came to get my packet I was told that 'since you registered so late you will have to wait to get your shirt'. I was then told that I would be emailed about the shirt and I never received an email. I was then told that I would receive a shirt in the mail by the race director and never received it. The Rexburg Community Affairs Department then told me that they would not mail me the shirt but that I could pick it up in Rexburg (I live in Pocatello). It was also inferred that I should have picked it up the day of the race. 2 months later I have still not received a shirt.
S. B. from salt lake city (6/11/2011) "Getting better all the time" (about: 2011) 11-50 previous marathons \| 3 Teton DAM Marathons COURSE: 4 ORGANIZATION: 4 FANS: 5 Nice day with overcast but a little warm. Gels were available this time, but I didn't take any until near the end, and there were NONE at mile 20 as promised, and then at mile 24 - they said 'we just gave the last one out'. How can that be when I was a top 5 finisher. OUT? How can that be? One aid station was out of cups, and holding the water jug up so thirsty runners could put their mouth under it. Awards were nice with engravings for the division 1st, 2nd, 3rd. Nice shirts too. The town hardly cares about this race, except for Sugar City, who places 100 American flags - Very Nice! The 30 or so home owners along the last 7 miles could get into it more, maybe play a boom box or ring a bell - anything. Race Director Michael and the staff have lots of enthusiasm and want to make this a community attraction. But this year, the town didn't seem too interested. Even my Rexburg family didn't watch, and the race goes near their house. Kind of sad. But the volunteers can sure cheer :) Keep it up Michael. I'll be back.
Tyson Poskochil from Lincoln, NE (7/8/2010) "Good, but still room for improvement" (about: 2010) 11-50 previous marathons \| 1 Teton DAM Marathon COURSE: 3 ORGANIZATION: 3 FANS: 3 I arrived early for the bus trip, which drives you out to the start at historic Teton Dam which flooded in 1976. Safety pins needed to be included in the packet, as none were available until you were about to board these buses. Temps were very cool at the beginning, but it warmed up gradually. The course was run through several potato farms, on both pavement and gravel, in a primarily rural setting. Hills are common in the final 7 miles, where you really don't need them. The minimal support along the way was good, but additional port-a-potties are necessary, as I saw three instances of female runners breaking off the public roadways and squatting wherever they saw fit. At the finish, the Great Harvest bread was good. However, I was disappointed to hear the medals awarded to the marathoners were the same as those awarded to the half marathoners, relay teams, and 10Kers. Although they are nice, I would recommend that they be slightly different in size; if nothing else, as they should distinguish the respective distances run by each participant. Kudos to Race Director Michael, who was just starting out but was very motivated and excited to undertake this event! As a patriot, I also enjoyed the line of flags as we ran through Sugar City. Nicely done!
