Every one of your three loops at Ragnar Trail Michigan starts from the lowest point of the course and tips past eleven percent within its first kilometre. Your share of this relay in the forests near Grayling is 16.8 miles, and the preparation has one main job: getting you into a climb cleanly, three times over, straight out of a rest.
The setting is the Hanson Hills Recreation Area near Grayling: forest of tall pines and maples, threaded with singletrack that runs fluently underfoot. A green, a yellow and a red loop meet at the same point and together add up to the 16.8 miles each of the eight team members contributes. The race stretches across two days and carries on from day into night.
That meeting point sits at around 350 metres, and the highest ground on the whole course reaches only about 395. So there are no big hills, but there is a fixed pattern: each loop leaves the low ground by a short ramp of some 30 metres of gain and ends by running back down to it.
The shortest loop measures just under five kilometres and is the most restless, since two more climbs follow its ramp in quick succession. The middle one, a little under ten kilometres, soon reaches the upper level and stays almost flat up there for a long way. The longest comes to just under 13 kilometres: after its ramp, a longer, gentler rise arrives around kilometre 18 of the overall count, the day's high point soon after, and from there the trail eases back to the start in shallow waves over some seven kilometres.

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.
The most delicate moment of every loop comes right at the start. You arrive from a rest with stiff legs and within a few hundred metres you are on a ramp that stands up past eleven percent. Power-hike the steepest metres and only start looking for your pace at the top. That costs seconds, while a ramp run too fast spoils the kilometres after it.
Your share is decided on the longest loop. Its long, barely falling closing kilometres only pay if you can truly run them, and that depends on how you came through the rise around kilometre 18. Hold back there, because any reserve you save is repaid for more than half an hour afterwards.
The trap is how easy the ground feels. With a span of only about 45 metres the course looks harmless, and fluent singletrack quickly carries you faster than planned, above all on the short loop. At night that stops being true: if one of your turns falls in the dark, steer by effort and not by your daytime pace.

Plan on roughly 2:30 to 3:45 hours of running, spread over three turns of about half an hour up to an hour and a half. The load is mostly aerobic, with short spikes on the ramps. Only a quarter of the course is level and the rest mostly lifts and falls gently, so you spend long stretches in one zone and are rarely properly rested.
The key stimulus is starting a climb with no run-up. Put 300 to 400 metre repeats on steep ramps into your hill sessions and begin them after just a few minutes of easy jogging, not after a long warm-up. Practise the switch from hiking back to running at the top as well, because that exact transition comes three times on race day.
The sequence itself belongs in training at least once: a weekend with three runs of about five, ten and 13 kilometres, spread over a little more than a day, one of them after dark. It teaches you how stiff legs feel after a long pause, and what you need to eat and do in between.
Since the race carries on into the night, go out several times with a headlamp on narrow forest paths until your eyes and your stride settle there. Finish long runs with a few kilometres at an even pace on gently rolling or falling ground, too. That prepares you for the end of the longest loop, where you are tired and still expected to run.
