So you’re probably an average human (no offence), because that’s how probability works. The average human walking pace is about 5 kilometers (3.1 miles) per hour; the average running pace is roughly 24 kilometers (15 miles) per hour. The most common lava is basaltic, which is as fluid and as free-flowing a lava as you’ll likely come across. These elements form the “framework” of the lava, so with less of them present, the lava less viscous, and it can flow faster. This is slightly faster than walking pace, but it’s a safe bet that you would be able to outrun it.
