The iconic marathon workout arrives for Inner Lane athletes 10 days out from the Chicago Marathon, offering one final fitness test and a challenging session before we settle into our taper. Yassos is based on the idea that an athlete aiming to run a 4:35 marathon should complete each 800m in 4 minutes and 35 seconds. The goal marathon pace shuffles to the goal time for each rep. While other tests show where your fitness is, this workout provides space for a final confidence boost and a strong training stimulus. 

Workout: 
1-2 mile warm-up 
10 x 800m @ goal marathon time - hour → minute
400m reset between reps
1-2 mile cooldown 

Office Hours is Inner Lane’s weekly track workout, designed by our coaches for our athletes and open to everyone willing to show up and work hard. Come meet us on the track!
