Tour de keys

I will be in Marathon from 11/18 to 11/22, then traveling from Marathon to Key West on 11/22 to check in, then get a flight out on Monday. I just read that Tour De Keys will be held that Saturday. Does anyone know where this begins and ends? Start times? Do they shut roads down? Any information would be helpful.

Good question. Here’s what I found on Tour de Keys in the Keys for November 22 — plus some helpful context, what to expect, and how it might affect you if you’re in Key West that day.

Event Details & Route

  • Tour de Keys on Saturday, Nov 22, 2025 offers two ride options:
    • A 100-mile century ride starting in Key Largo and ending in Key West.
    • A 50-mile ride that begins in Marathon and also finishes in Key West.
  • Start times:
    • Key Largo (100-mi): 6:44 AM — sunrise group start.
    • Marathon (50-mi): 9:30 AM for the group start.
  • There are supported rest stops every ~10–15 miles with hydration, snacks, restrooms, and SAG (support and gear) vehicles.
  • At the finish in Key West there’s a post-ride celebration (finish-line festival).

Road Closures / Traffic Impact

  • According to the ride’s “Ride Day Info,” U.S. Route 1 (the Overseas Highway) remains open to vehicle traffic during the ride. Riders are instructed to ride single file when necessary and follow deputy instructions at ocean-side crossings.
  • Because the route uses a major public highway (U.S. 1) rather than a closed course, you should not expect full road shutdowns.

Practical Tips & Things to Know

  • If you’re driving from Marathon to Key West on the same day (Nov 22), be aware of increased cyclist traffic, especially from mid-morning onward (after the 50-mile ride starts).
  • For solo travelers or non-riders, just treat Nov 22 like a busier day on U.S. 1 — allow extra time for potential slowdowns near rest stops or high cyclist density areas.
  • If you’ll be in Key West the night before or arriving on ride day, note that parking and traffic in Key West may be more congested as riders converge on the finish line festival.

Bottom Line: Tour de Keys is a supported charity ride from Key Largo or Marathon to Key West on Nov 22. While the roads are not fully closed, there will be many cyclists using U.S. 1, so you’ll likely see more traffic and should plan accordingly if you’re driving that day. The ride is well-organized, but it’s not a “race road closure” event — normal vehicular traffic continues.
