Part of the fun of being a marathoner is picking out your races each year. Another aspect of marathoning that is both fun and important is designing your strategy once you have registered for the race. Personally, I use elevation profiles to help me with both tasks.
An accurate elevation profile will show runners the nuances of gradient throughout a given course layout. Within 5 seconds, a viewer can answer the questions:
- Is the course hilly or flat? Is this course fast or slow?
- Does it give me a good challenge or is it too hilly?
- Can I achieve my goals on this course?
- How should I race this course?
- How should I train for this course?
When I create elevation profiles in support of my race course mapping, I aim to make them as clear and non-misleading as possible. After all, the profile can be one of the major factors that influences a runner to run the race. Every race has its own “personality” that should match up with the strengths and preferences of individual runners. Personally, I like downhill courses, but if the profile shows too steep of a downhill, I will not run it out of fear of injuries and diminishing returns on my finish time.
Three marathon courses in my fine state of Utah that offer fast, downhill layouts are the Ogden Marathon (May), Top of Utah Marathon (September), and the St. George Marathon (October). I have raced Ogden twice, Top of Utah four times, and St. George once, and they are all good P.R. courses — provided that you have trained for downhill!! If you have not engaged in a lot of downhill training, all three courses will eat you alive. I love these three races, though, and highly recommended them, especially St. George.
Since Top of Utah and St. George are both coming up within the next month, I decided to create a graphic that compares the profiles of the above three races.

Looking at the comparison, it is very clear that St. George should by far be the fastest course. Not only does it have the greatest elevation loss, but it is also at the lowest average elevation above sea level. Interestingly, St. George has the greatest elevation gain as well, as neither Ogden nor TOU have any hills even approaching the Vejo hill along Mile 8. The 400′ of total climbing at St. George is certainly nothing to sneeze at, and it really forces runners to train for both ups and downs.
However, it is NOT clear from this elevation comparison which is the faster course between Top of Utah and Ogden. Based on the total statistics and the profile line itself, it appears to be a complete wash. They both have virtually the same gain and loss, but are distributed differently. Personally, I like Ogden better, because much of the downhill is during the last 8 miles, whereas Top of Utah is rolling to flat during the last 8 miles. For me, this at least makes Ogden mentally easier. However, the top times at TOU tend to be faster than those at Ogden year after year. And if you poll 100 Utahns, most will tell you that TOU is faster. But when I look at the course profiles and evaluate my own experiences, I think they are almost identical in speed.
I wonder if TOU’s faster times are a result of simply being a fall race, whereas Ogden is a spring race? Training during Utah’s winters is often harsh, and perhaps most people do not get into peak shape until autumn. I think this could easily cause a “time bias” in favor of Top of Utah.
What do you think?

One final note of interest: The first 3.5 miles of all three races have identical elevation drops and gradients. Beyond being a cool coincidence, this fact is also useful in that you can uses your experience(s) in the other races to determine how fast to begin a race you have not run yet, or not run recently. First example, I ran 5:28/mile for the first four miles of the Ogden Marathon last May. Using estimates of fitness gains since May, and the fact of analogous gradients between courses for miles 0-4, I have determined that I should run the first four miles at St. George at 5:20/mile pace.
