The Tri-Cities Half: Flat, Shaded, and Honest. This Is PB Territory

The Course

21.1 km out-and-back on paved pedestrian park paths, starting and finishing at Columbia Point Park, same spot as transition. Official elevation gain is 44 m: in practice it's flat, with short rollers noted in athlete race reports. No walls, no elevation surprises. If the bike left you with legs, this is where you run fast.

Shade and Crowds: More Than You'd Expect

Two points in its favor compared to many late-summer 70.3s: there's plenty of shade through the parks, and spectator support is solid in the residential stretches and near the hotels. The out-and-back format also has a tactical advantage: you see who's ahead and who's behind, and you can count the gaps at the turnaround.

The Rough Asphalt and the T2 Problem

A practical detail multiple reports highlight: some asphalt sections in the parks are rough, and there are no mats in transition. Running barefoot from the rack to the run-out line hurts. Simple fix: keep your shoes right at your bike and get them on as soon as possible. Elastic laces instead of regular laces if you want to save seconds, but the priority is not trashing your feet before the half even starts.

The Weather: Two Possible Races

The official air temperature range is 9–30 °C (48–86 °F). In mid-September you could be running in 25–30 °C (77–86 °F) or on a cool day: in 2025 it was overcast, around 23–24 °C (73–75 °F), with rain on the run. Two scenarios, two plans:

• Hot scenario: go conservative for the first 5 km, use every aid station to cool down, take advantage of the shade in the parks. The out-and-back lets you recalibrate at the turnaround.
• Cool or wet scenario: this is PR day. Just watch the wet asphalt in the parks and don't go out too hard on adrenaline.

Pacing: How to Manage a Flat Half After 90 km of Wind

On a flat course the risk isn't the climbing: it's the steady pace masking fatigue until km 14–15, then presenting the bill all at once. Concrete strategy:

• First 3 km: 10–15 seconds per km slower than goal pace. Your legs are coming off a windy bike, let them come around.
• Km 3–15: goal pace, keeping an eye on cardiac drift.
• Last 6 km: decision time. If you're feeling good, this is when you move up; the out-and-back format tells you exactly who you can catch.

Ballpark time estimates (unofficial): 2:30 for a relaxed finisher, 2:05 for a mid-pack goal, 1:45 for a fast athlete, 1:30 for a top age-grouper.

What to Do Before the Race

Three concrete actions:

1. Test your shoes on rough asphalt: if you usually run on the track or smooth pavement, do a few long runs on rougher surfaces to see how your soles and feet respond. 2. Rehearse the two-scenario plan: one key workout in the heat and one in cool conditions, same goal pace, so you know how your body reacts. 3. Simulate T2 with no mats: in your transition practice, try putting your shoes on immediately instead of running barefoot with your bike in hand.

Bottom Line

This is a run leg that takes nothing away: flat, shaded, with crowd support. If you reach T2 with legs, the course lets you run to your true ability. Your only real job is not giving anything away beforehand: not on the rough asphalt barefoot, and not in the first 3 km run too fast.
