Race Preview: 2018 Timberline Marathon & Half Marathon

We all probably know by now how lucky we are to be surrounded by such beauty in the Pacific Northwest and I think as runners, we get to experience that so much more frequently than a lot of other people do. The Timberline Marathon & Half Marathon, which is the weekend of June 16/17, is said to be “the most picturesque marathon and half marathon trail running course in the Pacific Northwest” and that is really saying something!

Runners will get the full tour of Timothy Lake near Mount Hood and though this means you’ll be 3000 feet above sea level and running a very challenging race, the scenery will be the best reward a runner could ask for. One thing you might want to know if you decide to run the half marathon is that the distance is 14.4 miles rather than the usual 13.1. You’ll loop around the gorgeous lake and if you are running the full marathon adventure, you’ll get to do it twice. You can view the course map here. There are 3 aid stations along the course and the first one won’t be available until around mile 6.25. Runners should plan to bring their own hydration and nutrition needs to keep themselves fueled for the race. You can refill your water containers at the aid stations and there will also be Gatorade and toilets available here.

Matt ran this a few years ago and had this to say:

The course was magical with a combination of terrains. We started off downhill on some dirt trails before a very brief mini-scrambling section over larger rocks. After that, the rest of the race was completed on a very gently rolling, well-manicured, and superbly marked trail. We got to run in forest settings, over wooden bridges, along the lakeside beaches of Timothy Lake, and even across the dam itself.

After the event, there were tons of great refueling that catered to all kinds of runners – from those who want some fruit and granola bars, to those who feel the need to splurge on chips and cookies. There were on-site massages afterwards (available for a fee) that I immediately regretted not taking advantage of after I left.

Now that I know what the Timberline Marathon and Half are all about, I have absolutely zero issues with recommending it to those looking for a challenge in the forested beauty of the Mt. Hood Wilderness. They could make the “half marathon” 17 miles next year and I’d be even more ecstatic to join!

You have the unique opportunity to pick between Saturday or Sunday if you are opting for the half marathon. One will be on Saturday June 16th, starting at 10:00AM, and another will be on Sunday at 9:30AM. The full distance marathon will be on Saturday at 8:30AM. There will be a cut off time of 4 hours for the half marathon and 6 ½ hours for the full marathon. Walkers should not register for the marathon due to course support constraints, but are welcome to register for the half distance.

Please plan to bring insect repellent. Bees, yellow jackets, and other insects are lively and present this time of year at Timothy Lake, and you want to protect yourself. Also, if you are allergic to bee stings, it’s recommended that you carry your emergency medication with you, as this race is in a pretty remote location.

Awards will go to the top 3 male and female finishers and there will be age group awards for the top 3 as well. Everyone will get a technical shirt and a finisher’s medal.

The race will be limited to only 400 entrants for each event day, and it has a history of selling out. In other words, register now!!
