Major climbs and descents

Grandma's rolls gently downhill for most of its distance, with its sharpest single climb, Lemon Drop Hill, arriving late before the finish. Local routes should stay easy and rolling early, then rehearse one focused late climb.

What runners should replicate during training

A useful Grandma’s Marathon training route doesn’t need to match its distance -- it needs to reproduce the order and intensity of its climbs and descents. Match the course’s terrain rhythm above rather than picking any local hill at random.
