3. Avoid barn-burning
Going out too fast in any race is unwise, for Boston that holds exponentially true. “Many folks get ‘sucked’ into running faster then they should because of [the downhills] and then it will come back to bite you big time later in the race,” Beardsley says.
As you incorporate downhill running into your training, get a sense of what the efforts of different paces feel like on the decline. Factor this into your race-pace plan; a downhill mile may read faster but the effort is still there and downhill running is uniquely taxing.
