Race-morning weather history

Late April in Middle Tennessee is the warm-and-humid end of the spring calendar (typical start ~57F at 84% humidity, highs ~76F; 2026 ran hot). Spring convection is the live risk, though no edition is on record as stopped for weather. 2020 cancelled; 2021 displaced to November. Wyndo tracks what this calendar slot has actually served up at the start hour — temperature, dew point, wind, and rain — including the years when weather canceled or disrupted the race, and reads the live forecast for the start once the race confirms its schedule and race week arrives.

Race facts

Start line
Broadway at 8th Avenue, downtown Nashville; point-to-point finishing on Titans Way at Nissan Stadium across the Cumberland. Coordinates are the OSM intersection node — the corral stack extends west up Broadway. The 5K/10K start ~200 m south is a different line.
Traditional start (not confirmed for 2027)
7:20 AM (America/Chicago) — Carried from 2026 — official race-week page: '2027 final information will be available closer to race weekend'. Official 2026 road-closure brochure: marathon & half 7:20 AM CT on Broadway at 8th Ave; the 6:30 AM gun two blocks away (Demonbreun at 8th) is the separate 5K/10K, NOT an earlier marathon wave. No wheelchair/elite gun published; corral detail ships via the series app at race week.
Field size
2026 marathon finishers per FindMyMarathon (aggregator); marathon-only — the half, 10K, 5K and Sunday events together dwarf it.
Registration
open (Rock 'n' Roll Running Series price tiers; Remix/Tour Pass bundles; St. Jude charity entries)
