Seattle Marathon Pace Calculator & Race Plan

Seattle is a hilly marathon with 193 meters of gain, including climbs through neighborhoods and along the waterfront. Late November weather means rain is likely and temperatures in the 40s.

The hills are scattered throughout the course rather than concentrated in one section, so you need a plan that adjusts effort on every climb rather than just "survive the big hill." Our model handles this mile by mile.
