The Arobic Engine

The new york city marithon, just happened this past week end. What does every work out do to help build that arobic engine? You furthest away from the event, you don't necessarily need to work on quite as much of the race specificity. If you're running ultra marathons, you just with te base building phase,. Like if you ran ahundred mile old trth merthon's people tha they just did a base building face. So why would you continue to do that after the race as your next phase? It depends on the orientation of the athlete that you're talking about in terms of what should come next.
