Seville Half Marathon 2026: split times, aid stations and how to run it
The next edition is on Sunday 13 December 2026 (moved from 29 November because of the general election), starting in Seville (Paseo de las Delicias, Spain) at 9:00. Here you have the Seville Half Marathon route, split times for your target, what's at each aid station, how many gels to carry and the usual weather.
Seville Half Marathon: route and profile
Provisional route following the official 2026 course (there's no organisers' GPX). Start at 9:00 on Paseo de las Delicias; finish at the Buenos Aires roundabout, next to the start.
Climbs and descents
Sections of at least 400 m with a grade over 1.5 %, and how much a typical runner's pace changes at the same effort. Run by feel (or heart rate), not by watch pace.
| Section | Grade | At the same effort |
|---|---|---|
| km 15.8–16.7 | 1.7 % | +16 s/km |
| km 16.9–17.4 | -3.3 % | -20 s/km |
Route keys
- It's flat (between 2 and 32 m altitude along the whole course) and fast, one people choose for a PB. Start at your pace and hold it: there are no hills to win back what you give away early.
- The first 8 km circle the city to the south and east (La Palmera, La Borbolla, Ronda de Capuchinos) up to La Macarena and the Andalusian Parliament: wide avenues to settle into your pace without fighting the crowd.
- From km 8 to 17 you're by the river: you cross to La Cartuja over the Barqueta bridge, come back over the Cartuja footbridge and Torneo, and cross into Triana over the San Telmo bridge (km 14). It's the most wind-exposed stretch: find a group.
- Water and sports drink at km 5, 10, 15 and 18.5, and food at the finish. The organisers don't announce gels: carry your own and take them just before an aid station.
3 more keys in WinWatts: with the forecast for the days before, the wind and heat, and your split times at your pace.
Split times
At an even pace (the profile hardly changes anything), with the clock time counted from the 09:00 gun. If you start from a later corral or wave, add the time it takes you to cross the start. Write yours down or wear them on a pace band: watch GPS usually reads long.
| Point | 1 h 30 | 1 h 45 | 2 h | 2 h 15 |
|---|---|---|---|---|
| Average pace | 4:16 /km | 4:59 /km | 5:41 /km | 6:24 /km |
| km 5 | 0:21:17 9:21 | 0:24:50 9:24 | 0:28:23 9:28 | 0:31:56 9:31 |
| km 10 | 0:42:34 9:42 | 0:49:40 9:49 | 0:56:46 9:56 | 1:03:51 10:03 |
| km 15 | 1:03:57 10:03 | 1:14:37 10:14 | 1:25:16 10:25 | 1:35:56 10:35 |
| km 20 | 1:25:23 10:25 | 1:39:37 10:39 | 1:53:51 10:53 | 2:08:04 11:08 |
| Finish | 1:30:00 10:30 | 1:45:00 10:45 | 2:00:00 11:00 | 2:15:00 11:15 |
Aid stations: what's there and how much to drink
For a typical runner finishing in about 1 h 45: sip without stopping and take each gel just before an aid station, to wash it down with water.
| Where | What's there | Time (for 1 h 45) | You |
|---|---|---|---|
| km 5.0 | water, sports drink | 9:24 | ~200 ml |
| km 10.0 | water, sports drink | 9:49 | ~200 ml · gel just before |
| km 15.0 | water, sports drink | 10:14 | ~200 ml · gel just before |
| km 18.5 | water, sports drink | 10:32 | ~150 ml |
How many gels and how much to drink
What a typical runner (68 kg) needs depending on their time, with 35 g gels. When running the stomach tolerates less than on the bike: more than 60 g of carbs per hour only if you've trained it. Gels alone don't reach that figure (the first one comes around 45 minutes and none are due in the last half hour): the rest comes from drinking sports drink instead of water at a few aid stations.
| Time | Carbs per hour | Gels | Total drink | Sodium per hour |
|---|---|---|---|---|
| 1 h 30 | 60 g/h | 1 × 35 g | 0.8 l | 300 mg/h |
| 1 h 45 | 60 g/h | 2 × 35 g | 0.9 l | 300 mg/h |
| 2 h | 60 g/h | 2 × 35 g | 1.0 l | 300 mg/h |
| 2 h 15 | 60 g/h | 2 × 35 g | 1.1 l | 300 mg/h |
Nothing new on race day: gels, breakfast, shoes and socks, all tested on your long runs. Vaseline on your feet, groin and armpits, and protect your nipples. If it's cold at the start, wait in your corral in old clothes you can throw away.
Seville Half Marathon: winter weather (late-January editions)
What the weather was like during the race (from 9:00 to the finish of a 1:52 runner) in recent editions, which were held in late January:
| Year | Low | High | Rain | Max wind |
|---|---|---|---|---|
| 2024 | 9 ºC | 10 ºC | 0.0 mm | 10 km/h |
| 2025 | 13 ºC | 15 ºC | 0.9 mm | 17 km/h |
| 2026 | 12 ºC | 12 ºC | 4.9 mm | 19 km/h |
When running, heat slows you down: allow roughly 2 % more time for every 5 ºC above 12 ºC.
Your Seville Half Marathon, tailored to you
This guide uses a typical runner. In WinWatts we calculate it with your data:
- Your time, your pace and your split times from your threshold pace and the expected heat.
- The race-day forecast, and what to wear at the start and during the race.
- How much to drink at each aid station and where to take each gel, with your own gels.
- Your training plan until Sunday 13 December 2026 (moved from 29 November because of the general election), adjusted every week to how you're doing.
WinWatts is not affiliated with the organisers of the Seville Half Marathon. Dates, routes, schedules and registration: official website. Provisional route: a Wikiloc user's GPX that follows the official 2026 map and street list (the organisers don't publish a GPX); aid stations from the 2026 rules; weather from past editions (Open-Meteo).
