| | Cool Running :: Yasso 800s (Site not responding. Last check: ) |
 | | First, 800s are OK as a repetition length in speedwork for marathoners, but the recoveries are too long and the session is therfore not challenging enough. |
 | | The efficacy of the Yasso 800s vis-a-vis other workouts will depend in part on your own recent running background (read: mileage) and on your basic abilities (i.e., do you have more talent for middle distances or are you a natural long distance runner?). |
 | | As a general rule, though, Yasso 800s are slightly too fast relative to the pace which brings you to your lactate threshold (LT), and they are too slow relative to the pace which elicits your VO2max. |
