Swimming from Alcatraz Island was once thought to be impossible. This year, nearly 1,000 athletes will make the treacherous swim, fighting the strong currents and ever looming fear of what lies below the water's surface. This is certainly not a race for the faint of heart. The swim will start the journey but the hills of San Francisco may just be the hardest section on the course: it boasts sharp turns, fast descents and agonizing climbs to test the aerobic endurance and mental fortitude of every athlete.
Next racers get to take in the scenic views of the San Francisco Bay and Golden Gate Bridge as they weave their way back to the finish line on the demanding run course. Throw in a beach run with a 400 step sand ladder at the end - it's a race you won't want to miss out on!
