About the Base 2 Space
This is a stair climb up the Space Needle, not a road race. Two open-air staircases spiral up the outside of the structure, and you take an elevator back down from the observation deck at the top. The views open up as you go, with the city, the water, and the mountains coming into frame on the way up. The climb is a fundraiser for cancer research.
Dress for outdoor conditions, since the staircases are exposed to the weather. You can go up more than once if you want; there is a separate check-in tent for additional climbs.

Finish-Time Stats
Going by the 2025 results, this is a big field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The Base 2 Space has been held every year since at least 2015. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
