Welcome back to Pump Track Saturday! For Episode 12, we’re stopping in Richfield, Washington to check out what might just be the smallest city pump track ever built. Seriously, is this a track for ants? While rolling up the I-5 corridor looking for new spots to add to the Pump Track Locator, we couldn't resist pulling over to see if this bite-sized asphalt track is actually rideable on a BMX. It’s definitely compact, but we’re here to give it a full review and see how it flows.
