If you thought the first stage of the face-off between competitive triathletes Tony and Casey in Part 1 of our three-part Reebok: Live with Fire video series was grueling, you ain't seen nothing yet.
In conjunction with Reebok and their new ATV19 running shoe, we present Part 2 of Tony and Casey's epic battle as the guys take on a training beast — the world famous Santa Monica Stairs. This previously quiet set of seemingly unassuming stairs in the Santa Monica Canyon aren't so quiet anymore — workout fiends have made it one of the hottest places anywhere to push your body to its limits.
Thankfully, Tony and Casey aren't afraid to take on those 172 steps (each way) and get the full grip on what the ATV19's can do for the serious athlete.
Check out what happens above.
