Sunday’s full marathon and the Convention Center finish
The organizer-linked registration schedule gives May 30, 2027 at 06:30 for the full marathon. The wider weekend begins on May 29, including the Saturday 5K and children’s activities. Use the Sunday full-marathon entry when calculating your training start and arrival day; the first date in a weekend banner is not the marathon date.
The route description connects the waterfront and KeyBank Center with Buffalo’s parks and neighborhoods. Its landmarks include Lake Erie, Forest Lawn Cemetery and the Olmsted park system. Study the final full-distance map for the split from the half marathon and any changes, rather than treating the shared starting area as evidence of identical routes.
The start and finish being close together can simplify accommodation and meeting plans, but road closures still affect access. Locate the Convention Center entrance used for packet collection separately from the finish chute. Choose a reunion point outside restricted athlete areas and confirm the final expo hours before arranging a late arrival.
The official site also advertises a November 14, 2026 community run; that is not the next full marathon. Registration lists a minimum age of 18 for the marathon. Check the final participant instructions for cutoff, aid products and bag handling, then practise the relevant routine within your existing training rather than guessing from another city’s race.
