Double Marathon Allen, United States of America · Thursday 31 December 2026
Running the New Years Eve Double Marathon in Allen will feel remarkably easy on your legs, which is both a blessing and a potential trap. The course sits between 192 and 203 meters above sea level with virtually no meaningful elevation gain, so you won't battle any real climbs. What you get instead is a genuinely flat to gently rolling landscape that lets you settle into a rhythm early. The Allen area around the race route is typical North Texas geography, characterized by straightforward road running through suburban and semi-developed terrain. You'll notice the landscape doesn't offer much visual drama, which means you're running for the pure pleasure of running rather than being distracted by scenery. The relative flatness means your GPS watch won't show the dramatic pace variations that hills create, but it also means there's nowhere to hide if your fitness isn't there. Because you're racing on December 31st, the weather will be unpredictable in that particular North Texas way. It could be cool enough for a light jacket or mild enough that you're shedding layers by mile ten. The lack of elevation change means temperature swings will affect you more directly since you won't get the cooling effect of descents. Running a double marathon here means committing to two full loops or an out-and-back configuration, so you'll become extremely familiar with every turn and building on the route. This repetition can actually work in your favor on the second marathon when fatigue sets in, because your brain already knows what's coming. The roads should be clear of holiday traffic on New Years Eve, giving you a peaceful, straightforward running experience where the main challenge is purely your own legs and mind pushing through 42.2 kilometers.
