My fastest marathon didn’t coincide with the typical training story of having the most logged miles and vigorous training leading up to race day. Heading into the Mountains 2 Beach marathon, I had been averaging about 20 miles per week, but had sufficient cross training to feel comfortable with my aerobic capacity to be able to run the marathon. My marathon race strategy seemed a little unconventional – to pace myself for the first half according to the highest pace at which I could maintain nasal breathing.
