Tampa Bay 100 Mile Endurance Run

Event Overview

Course & Terrain

Point to point in four segments: Tampa (about 30.6–31.1 miles), Dunedin (22.7), Clearwater (29.4) and St. Petersburg (19.7), about 102.4 miles in all by UltraSignup’s figures. Runners navigate by direction cards and the organizer’s CalTopo map; the course is not marked like a trail race. The St. Petersburg segment and finish changed for 2025 and 2026.

Key course features to know before comparing this race:

• Ybor City start in Tampa
• Courtney Campbell Causeway across Old Tampa Bay
• Dunedin, Clearwater and the Gulf beach towns
• Finish at Coffee Pot Park on St. Petersburg’s waterfront

Sidewalks, multi-use paths and bike lanes, with road crossings in open traffic. Mandatory gear: phone, 20 oz of water, headlamp with spare batteries, reflective gear, front and rear blinking lights and the CalTopo app.

November is Tampa’s driest month, with an average high of about 79°F and low of 61°F and humidity around 75%. Much of the course is exposed to sun and wind off the water.

Entry & Logistics

Why This Race Matters

Skunk Ape Events and race director Joseph Fuller started the Tampa Bay 100 in November 2023. The organizer calls it a self-guided endurance tour rather than a race, but it records finish times and gives awards to the top four men and women and buckles to every finisher. It is one of the few 100-milers in the US run almost entirely on city sidewalks and bike paths, through four cities around the bay. Finishers have grown from 48 in 2023 to 55 in 2025.

Historical benchmark notes in the directory record (verify current records with the linked official sources):

• Men: 17:17:00, Andrew Kelly, 2025, per UltraSignup and the 2026 guidebook. DUV lists the same time and hometown under a different runner, Rob Raguet-Schofield.
• Women: 20:43:19, Sarah Raaymakers, 2023, third overall.
• The St. Petersburg segment changed in 2025 and the finish moved again for 2026, so times are not on an identical course.

Preparing for a Race Like Tampa Bay 100 Mile Endurance Run

The 100-mile race guide covers the format as a whole. These guides go deeper:

• Walking strategy for ultramarathons: When and how to walk by terrain, effort and cutoffs.
• Crew and aid-station strategy: Crew tables, aid stops, drop bags and runner preferences.
• Gut training for ultrarunners: A six-week practice sequence for race-day fueling.
• Tapering for ultramarathons: Plan the taper and race week around your own recovery.

Best Fit

• Runners wanting a first 100 with a generous time limit
• Crews who want to see their runner often
• Road runners who would rather avoid technical trail

Planning Notes

• Treat intermediate cutoff gates as part of the course. Build enough margin for aid stops and late-race slowdown, and verify every current gate in the official rules.
• Repetitive surfaces can expose fit, friction, and loading problems. Check in when symptoms or conditions change, and use only footwear already tested for the course.
• The directory marks this as having comparatively simpler logistics. That editorial label is not a safety rating; verify cutoffs, terrain, support, crew access, and withdrawal procedures.
• Self-navigation on city streets: download the CalTopo map
• Traffic and road crossings, especially at night
• Indian Rocks Beach aid is unstaffed after 2 AM
• Point to point: arrange the trip back to Tampa
