SPAR Budapest Marathon course & pace calculator
A loop from Lágymányos in south Buda along both banks of the Danube, through the Buda Castle tunnel and over the Chain, Liberty and Árpád bridges. Flat along the river, with short bridge climbs and a rise through the castle district early on. This profile uses a third-party GPX for the 2026 edition.

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 09:00 start, from 98 mornings within three days of the race date since 2011 at FERIHEGY, HU. Cool and warm are about the 10th and 90th percentile mornings by heat stress. Median wind 13 km/h.
Weather scenarios use a 09:00 start.

Data & method
- Route: Third-party 2026 reference GPX from GoAndRace (https://www.goandrace.com/en/map/2026/10/41th-spar-budapest-marathon-2026-course-map-1.php); not verified against the organizer's current-edition route. Measured at 42.16 km and scaled to 42.195 km.
- Elevation: Copernicus GLO-30 DEM (30 m), © DLR e.V. 2010–2014 and © Airbus Defence and Space GmbH 2014–2018, provided under COPERNICUS by the European Union and ESA. 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 12839099999).
- 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 SPAR Budapest Marathon hilly?
The course climbs about 131 m (430 ft) and descends about 131 m in total, which is gently rolling. At even effort the terrain alone changes a 3:00 flat-course marathon by +0:57 and a 4:00 by +1:17.
What flat-course time do I need to break 3 hours at the SPAR Budapest Marathon?
About 2:58:36 on a flat course, assuming a typical race morning. For a sub-4 you need about 3:57:43. Switch the weather off in the calculator to see the terrain-only figure.
What is the weather usually like at the SPAR Budapest Marathon?
On a typical race morning it is about 12°C (54°F) at the first wave’s start and 16°C (61°F) three hours later, with a dew point near 8°C. That costs a 3-hour runner about 0:28 and a 4-hour runner about 1:03. 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.
