About the Mash + Dash - 5K, 10K, 10-Miler, Half Marathon
The course runs along the beach path at Alamitos Beach, staying on the water the whole way. It is an out-and-back on a shared path, so you will have company beyond just other racers. Several distance options are available, with the shorter routes forming the building blocks of the longer ones. The path is paved and flat, with the coast the whole way.
Packet pickup runs the afternoon before at a sporting goods store in Long Beach, with bib pickup also available at the start on race morning. Parking in the lot nearest the start is paid by the hour; street parking nearby is free. Staff at the registration tent will hold personal items if you bring your own bag.

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

The Mash + Dash - 5K, 10K, 10-Miler, Half Marathon has been held every year since at least 2023. 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.
