Course Recon Is Ultramarathon Training

I am probably more obsessive about course recon than most coaches. If several people on Team SUC are training for the same race, I want us on that course. I want to know which climb looks harmless on the elevation profile but feels terrible, where the exposed miles begin and whether the “fast finish” is actually runnable after the rest of the route.

This is not only about reducing race-day nerves. A course preview can be one of the most specific long runs in the training block because the physical work and the planning happen at the same time.

We have used this approach for Salmon Falls, Canyons, Western States sections and Rio Del Lago. The more complicated the race becomes, the more useful it is to replace assumptions with actual trail knowledge.

Elevation profiles hide a lot

A course profile can show the length and gain of a climb. It does not show whether the grade is smooth enough to run, covered in loose rock or broken into a series of short punches that never let you settle.

The same thing happens with descents. A long downhill looks fast until you discover the turns are tight and the footing demands constant attention. A flat section may be exposed, sandy or much slower than the map suggested.

Running the trail lets you build the race plan around effort instead of a picture. You can decide where hiking makes sense and which section deserves patience. When you return on race day, the course still hurts, but it is no longer surprising you in the same way.

Aid-station distance is not aid-station time

Five miles between aid stations might take 50 minutes on one section and twice that on another. That changes how much water you need and when you should eat.

During recon, pay attention to the time between practical refill points. Notice where the trail becomes exposed and whether you are likely to be there during the warm part of the day. If the section has a long climb, practice eating before it instead of waiting until your breathing is too high and nothing sounds good.

This is where I want runners using the same vest, bottles and fuel they plan to race with. If the pack is difficult to refill or one bottle position annoys you after three hours, finding out during training is useful. Finding out at mile 35 is just irritating.

Preview the parts that can change your race

You do not need to cover every mile. For a 100-mile race, forcing the whole course into one enormous training weekend may create more recovery cost than useful information.

Choose the sections where decisions matter. That may be the longest climb, a technical descent late in the race, the night section or the final miles where you hope to run. A confusing intersection is worth seeing. So is a crew location if your team needs to understand parking and access.

For Project RDL, we use multiple course runs because Rio has several different problems. A long on-course day teaches the route and fueling. The night run covers lighting, focus and how familiar trail changes after dark. Those sessions belong to the same race plan, but they do not need to happen all at once.

Give the run a question

“See the course” is not enough of a goal. Before starting, decide what you are trying to learn.

Maybe you want to find out whether the big climb can be hiked below your red line. You may need to test how much fluid the exposed section requires or whether poles are worth carrying. If the final miles are supposed to be runnable, arrive with some fatigue and see whether that is true for you.

Write down the answer afterward. Race planning gets much easier when it is based on your own notes instead of a collection of guesses and somebody else's splits.

Do not accidentally race the preview

Course days are exciting. The group is together, the route matters and every Strava segment is waiting to turn the workout into something it was not supposed to be.

Keep the effort connected to the question. If the goal is navigation and gear, run easy enough to pay attention. If the goal is race-specific climbing on tired legs, then fatigue may be intentional. Those are different sessions.

The fastest recon is rarely the most informative. Blowing up on the preview can teach you something, but we do not need to repeat that lesson every weekend.

Turn the trail into a usable plan

After the run, divide the course into sections you can remember. Aid stations are convenient, but terrain changes may be more useful. For each section, note the expected time range, whether you plan to run or hike, what you need to carry and the biggest thing that could go wrong.

Keep the final plan simple enough to use while tired. “Stay controlled to the top, refill completely and eat before the descent” is useful. A page of exact splits can fall apart as soon as the weather changes.

Course knowledge should make you more adaptable, not lock you into one perfect version of race day.

When you cannot get to the course

Travel, snow and access rules can make recon impossible. Use the official map, aid-station chart, recent race reports and whatever current video is available. Then find local terrain that asks a similar question.

A Sacramento runner preparing for a mountain race can use Auburn for the climbing and descending, then schedule a few Sierra days for altitude. It is not the same as the race course, but the training becomes much more specific once you know what you are trying to copy.

Always confirm access before running a published race route. Event-day permits do not automatically create year-round public access, and conditions or closures may have changed.

Know it, then respect it

Recon does not guarantee a finish. Ultras are still messy, and the conditions you get on race day may be completely different from the preview.

What recon gives you is a better set of decisions. You have seen the terrain, practiced the equipment and already learned where your first plan was wrong. That is real training.

Team SUC race blocks include course-specific long runs whenever access allows it. You can learn more about Team SUC or check the next public SUC run to see where we are training.
