At Ragnar Trail Atlanta you run as one part of a relay team: your share is 15.8 miles, split across three loops through dense pine at Georgia International Horse Park in Conyers. So the preparation is not for one long run but for three separate efforts, the last of which should go as well as the first.
The setting is Georgia International Horse Park in Conyers, and the dense Georgia pine gives the course its character. The map shows a green, a yellow and a red loop, all starting and ending at the same point. Together they make up each team member's 15.8 miles, and the team as a whole covers 126.4. Between your loops, the others are out on course.
The shortest loop measures about seven kilometres and is the calmest, a gentle up and down with no ramp worth the name. The yellow sits in the middle at around nine. It climbs early for nearly 700 metres, then stays almost level for a long way before lifting again at its far point, with a 300-metre kick at close to ten percent, the steepest piece of the whole course.
The longest loop, just over ten kilometres, is the most restless. Over its opening kilometres one short climb follows the next, after which the rollers ease. There are no big hills anywhere: the course stays in a narrow band between just under 200 and just over 230 metres, and the work lies in the constant changes. Two water stations sit on the course, one on the yellow loop, the other serving red and green.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Do not treat the 15.8 miles as one continuous run. Each loop is its own effort with a break after it, so you can go quicker than the total distance suggests, but only so quick that the next loop does not suffer. For the team, three solid efforts count for more than one brilliant and two laboured ones.
The longest loop is where most can be gained or lost. Its short climbs come so close together that little recovery fits between them. Run them at an even effort rather than an even pace, carry yourself easily over the crests and save any push for the flatter kilometres back to the starting point. If it falls last in your rotation, it becomes the real test.
The trap is the start of every loop: you set off rested and quickly overdo it. On the yellow, the longest climb of the course comes early, and if you run it hard you carry that across the level kilometres all the way to the steep kick. Feel free to walk that kick, since 300 metres cost little time on foot and a lot of strength at a run.

Expect roughly two and a half to three and a half hours of running in total, spread over three efforts of about 40 to 85 minutes. The load is mostly aerobic, with short harder spikes on the climbs. Around a third of the course each goes up, down and level, so long stretches in one rhythm are rare.
The defining feature is the repetition: run, stop, run again on stiff legs. That belongs in your training. Put several runs on the same day, a few hours apart, with a combined distance that approaches race distance in the final weeks. Two days like that show you how your legs respond after a break and what you can eat and drink between efforts.
For the tight rollers of the longest loop, use short hill repeats of 30 seconds to two minutes: push up and keep running over the top without a pause. That practises what counts here, finding your pace again straight after a crest. Add brisk walking on steep ramps around ten percent, so the short kick on the yellow loop does not knock you out of rhythm.
The April date puts your main build in January to March, so secure your long sessions early in the year and run as many of them as you can on trails rather than tarmac. Because the whole course makes do with two water stations, it also pays to use your longer runs to work out how you want to manage your drinking over ten kilometres.
