A runner takes the ASICS LA Marathon treadmill challenge at the Third Street Promenade on Tuesday, March 4, 2014. The one-of-a-kind custom-built treadmill with a safety harness runs at only one speed, the LA Marathon course record of 2:06:35, which equates to a 4:50 mile. Most runners can’t make it more than a couple of minutes on the treadmill.
