How does running 20-23 miles at 7:30 pace teach one to hold 5:30 pace or faster for a marathon? Why not just build in 3 hour long bike rides or eliptical workouts to build mitochondria or optimize glycogen utilization and fat burning? (The cardiovascular system can't differentiate between activities) There are multiples ways to approach any problem.
