the guy now I'm coaching you know I want the guy who can run 49 seconds for a 400 like that's the kind of speed you have to have now you don't have to have that speed while you're doing marathon training but you need to have had that speed before that like as a kid growing up that's why like with kids I'm like get as fast as you can because if you want to be a world- class marathoner I need 49 second speed right like that's the kind of speed that Kip chogi has and then that carries you on to be able to run a great mile to be able to run a great 5K like it's all built off speed like that's what we work on on with training it's like let me develop your 5K speed your mile speed first which is directly correlated to your Sprint speed let me develop all that and then we'll grow that into 10K speed then we'll grow that into half marathon speed then we'll grow that into Marathon speed but marathoners are they have wheels
