Walt Disney World Half Marathon course & pace calculator
The Saturday half of the Walt Disney World Marathon weekend, running from Epcot out to the Magic Kingdom and back. Flat, on park service roads, and finished well before the Florida heat builds. This profile is a Strava segment, so treat it as third-party reference geometry.

Heat is scored with shade WBGT from temperature and humidity, starting to cost time above about 15°C (59°F) WBGT. Slower runners lose more because they are out longer. Wind, sun and rain are not modelled.
Certified distance only. Switch on to count the metres lost to corners, crowds and aid stations.
Same effort all the way: slower up the climbs, faster down the descents.

Race-morning weather
Air temperature and relative humidity by hour from the first wave’s 04:30 start, from 102 mornings within three days of the race date since 2011 at ORLANDO KISSIMMEE MUNICIPAL AIRPORT, FL US. Cool and warm are about the 10th and 90th percentile mornings by heat stress. Median wind 11 km/h.
Part of the Disney World race weekend, starting in the same morning block as the marathon; the scenarios use the marathon's start time.

Data & method
- Route: Strava segment for the disney half (https://www.strava.com/segments/41526408), exported as GPX; user-drawn rather than organizer-published, so it is third-party reference geometry. Measured at 21.36 km and scaled to 21.0975 km.
- Elevation: USGS 3DEP 1/3 arc-second (10 m) bare-earth DEM. Sampled every 25–50 m, with bridges set to deck height and smoothed over 200–400 m.
- Weather: hourly observations from NOAA’s Integrated Surface Database (station 72201192813).
- Small climbs on flat courses can be terrain-model noise; they add only seconds to the estimates.
- This reference GPX has not been verified against the current edition. Check the organizer's latest course map before using its pacing plan.
Frequently asked questions
Is the Walt Disney World Half Marathon hilly?
The course climbs about 42 m (138 ft) and descends about 42 m in total, which is flat. At even effort the terrain alone changes a 1:30 flat-course half marathon by +0:15 and a 2:00 by +0:20.
What flat-course time do I need to break 1:30 at the Walt Disney World Half Marathon?
About 1:29:36 on a flat course, assuming a typical race morning. For a sub-2 you need about 1:59:28. Switch the weather off in the calculator to see the terrain-only figure.
What is the weather usually like at the Walt Disney World Half Marathon?
On a typical race morning it is about 13°C (55°F) at the first wave’s start and 13°C (56°F) three hours later, with a dew point near 11°C. That costs a 1:30 runner about 0:09 and a 2-hour runner about 0:12. Figures come from airport observations within three days of the race date since 2011.
How is the course-adjusted time calculated?
The course is cut into 100 m pieces. Each piece is run at your flat-course pace times a grade factor (about +3.3% per 1% uphill and −1.8% per 1% downhill) and a heat factor from shade WBGT at the time you reach it. Adding the pieces gives the course time, and the calculator works backwards from a goal the same way.
