The 70.3 Oregon Half Marathon: Flat, Shaded, Runnable Start to Finish

The Course

21.1 km, fully paved, laid out as a double figure-eight/out-and-back through the Minto Brown Island Park nature reserve and along the Willamette River. It starts and finishes at Riverfront Park, which is also where transition sits: zero shuttling, spectators concentrated in one spot.

Official elevation gain is ~75 m. Other sources list ~96 m. Either way: nearly flat. No walls, no quad-shredding descents. This is a course where your open half-marathon pace off the bike is realistically within reach — if you come off the bike with your legs intact.

Shade Is Your Best Friend

The key stat for this race: the average July high in Salem is 31 °C. The run starts with the sun already high. The good news is the course through Minto Brown is largely shaded, with only a few exposed sections. After 90 km of riding in the sun, entering the park is the relief of the day.

Concrete strategy for the exposed stretches:

• Ice in your kit at every aid station before a sunny section.
• Water over your head at the start of the exposed stretch, not at the end.
• Don't surge in the shade to "make up time": hold steady pace, let the perceived temperature drop, not the pace climb.

Aid Stations

They're well spaced and well stocked: water, electrolytes, cola, chips, gels, fruit and — critical in July — ice. On a double figure-eight course you hit them regularly. Decide before the race what you'll grab at each aid station and in what order: whoever improvises at mile 8 in 31 °C heat usually gets it wrong.

One advantage of the out-and-back/double figure-eight format: you see other athletes multiple times, and you know in advance what's coming on the next lap. Use the first pass to memorize where the exposed sections and aid stations are.

Pacing: This Is Where the Race Is Decided

On this course there are no elevation excuses. There's only one variable: how much you spent on the bike and how hot it is. Rough (unofficial) estimates put the run split between 1:28 for a top age-grouper and 2:30 for a relaxed finisher.

Game plan:

• Km 1-3: start 10-15" per km slower than goal pace. The relative coolness of the park is deceptive: your body is still processing the bike.
• Km 3-16: goal pace, steady. Fixed ritual at every aid station: ice, drink, douse.
• Km 16-21: if you've managed it well, the flat course lets you close strong here. If you overcooked the bike, this is where you pay for all of it.

The Test to Run Before Race Day

If you can in the weeks before the race, train during the hot hours and rehearse the ice/hydration protocol in a brick: 60-90' on the bike at race intensity followed by 30-40' of running at goal pace, practicing exactly what you'll do at the aid stations. Race day is not for experimenting — it's for executing.

The Decision to Make

This run rewards those who arrive intact and punishes those who played hero on the bike. Decide today: your run split goal, the corresponding pace, and the bike power cap that makes it possible. Then, on race day, trust the plan. The course will do the rest: it's one of the most honest places to close out a 70.3.
