Athens Marathon 2026 fueling guide: water stations, gels, and the long climb to km 31

The Athens Marathon The Authentic starts at 08:30 on Sunday, 8 November 2026, and gives you 15 stations on the way from Marathon to the Panathenaic Stadium: water every 2.5 km, isotonic drink every 5 km from km 10, and energy gel only twice, at km 10 and km 20. That is enough water, but not enough carbohydrate for most runners. And the route climbs, in sections, from about km 11 to the Stavros junction at km 31. So most of your fuel has to come with you, and the plan has to work while you are running uphill. This guide shows what the organizer has published, when you will reach each station at your pace, and three plans to choose from.

Athens is not a fast course. The first 10 km are flat or slightly downhill, then the road rises for about 20 km before a long run down into the city. A 2:50 racer and a 7-hour walker pass the same tables, but at very different times and with very different needs. The station list below comes from the official 2026 race page. Block start times are only final two weeks before the race, so check everything again in race week.

Athens Marathon 2026: the confirmed race facts

The cut-offs are clock times of day, not times from your own start. Runners who pass a station after its time are not pulled off the course, but they must move to the pavement and continue at their own risk, because the police reopen the road to traffic behind the last runners. A bus follows the field and picks up anyone who wants to stop.

The official table also lists 7.5 km (11:11), 12.5 km (12:08), 15 km (12:34), 17.5 km (13:04), 20 km (13:33), 22.5 km (14:02), 27.5 km (14:58), 32.5 km (15:59) and 37.5 km (16:53). If you are in one of the last blocks, the early checkpoints are the tight ones: the 5 km time leaves little room after a 10:09 start. The race page does not explain how the early cut-offs apply to the last blocks, so ask at the expo or check the official app if you expect to be near them.

What is on the Athens Marathon course

The race page lists an isotonic drink and an energy gel but does not name the brand or the grams of carbohydrate. Most isotonic sports drinks are about 6 to 8 percent carbohydrate, so the 100 to 150 ml you get down from a cup gives roughly 6 to 12 g. That helps, but seven cups do not replace your own gels. Treat the two course gels as a bonus unless you know exactly what will be handed out and you have used it on a long run. Look for the brand at the expo, and buy a few to test if you can.

When you will reach each station at your pace

The table shows elapsed time from your own start for an even pace. On this course nobody runs even splits: you will be a few minutes behind these times on the climb and catch up on the way down after km 31. A 3:00 runner reaches the second course gel at 1:25; a 6:00 runner gets there at 2:51. Add your block start time to see the clock time. A 5:00 runner in a 09:45 block reaches km 30 at about 13:18.

Pick your plan: three runner profiles

World Athletics’ consensus statement gives 30 to 60 g of carbohydrate per hour as the common marathon range and suggests trained runners try up to 90 g per hour for events over two and a half hours. Research on multiple transportable carbohydrates shows that intakes above 60 g per hour are only absorbed well when the product mixes glucose and fructose and the gut has been trained for it. So instead of one number for everyone, here are three honest profiles. With 25 g gels, one every 30 minutes gives 50 g per hour, every 25 minutes gives 60 g, and every 20 minutes gives 75 g.

Racing it: your problem is breathing, not just volume. At 75 g per hour from gels alone, a 3:00 race needs nine 25 g gels. On the climb from km 17 to km 31 you breathe harder and gels are harder to swallow. Take them on the flatter sections or at a station with water, not halfway up a steep ramp. Take the first gel about 20 minutes in, one at the 20 km station, one before km 30, and the last one around km 35, once the road starts to drop. Build your number over eight to ten weeks of hilly long runs, starting at 60 g and adding 10 to 15 g every second week while your stomach stays quiet.

Steady marathon: think in grams. A 4:00 race at 60 g per hour is 240 g. Seven cups of isotonic drink give maybe 40 to 60 g if you drink most of each one. If you know the course gel, the two at km 10 and 20 add two more. That leaves about six to seven carried 25 g gels. The climb makes the middle of the race slower, so fuel by the clock, not by the kilometre: from km 20 to km 31 you cover less ground per gel.

Long day: seven or eight hours on the course changes the math. Fifty grams per hour over seven hours is 350 g, and the course gives you only part of that. Small, frequent doses work best: a gel every 30 minutes, or half a gel every 15, with a piece of banana at km 20 to 35 and cola from km 30 when a gel feels like too much. Eating on schedule in the first two hours is what keeps you walking strongly up to the Stavros junction.

Caffeine, sodium, and the late stations

• Caffeine: the ISSN position stand supports 3 to 6 mg per kg taken about 60 minutes before exercise. A 70 kg runner is at 210 mg with 3 mg per kg. With a long wait in Marathon, take it at the start area, not on the bus, so it peaks during the race.
• A caffeinated gel taken around km 25 to 28 lands just as you reach the hardest climb at km 30 to 31. Only do this if you have tried caffeine late in a long run.
• Sodium: isotonic drink at every 5 km station from km 10 gives some sodium. In cool weather that is often enough. Salty sweaters on a warm day may still need a tested salt product.
• Salty snacks at km 30 and 35 add salt, but they are dry and slow to eat while breathing hard. Coca-Cola at km 30, 35 and 40 is the easier late carbohydrate if you have used it before.
• Tear the top of your gel before the station, so you can drink with the same hand.

Hydration for a November Day in Athens

Long-term averages from the Hellenic National Meteorological Service for Athens in November are a high near 19 °C (66 °F), a low near 12 °C (54 °F), humidity around 69 percent, and about 11 rainy days in the month. Sunrise on race day is a little before 07:00, so the morning in Marathon is cool. But a 6-hour runner in a late block is on the course through the warmest part of the day, often in sun, and sunset is around 17:20, so the last finishers come in at dusk. World Athletics warns against drinking more than you sweat; finishing heavier than you started is a sign of overdrinking.

• Test your sweat rate in one cool and one mild long run before race week.
• Pick your priority stations now. With one every 2.5 km you can skip some.
• There is no bag at the start, so bring a throwaway layer. Clothing bins in blocks 2 to 5 collect it for a social cause.
• Late blocks: you climb in the warmest hours of the day, so plan to use more stations after km 20.
• Seek help at a medical point for confusion, severe headache, repeated vomiting, or collapse, whatever the clock says. There is medical cover at almost every station.

Breakfast for an 08:30 to 10:15 start

A familiar carbohydrate-rich meal one to four hours before racing is the standard framework in the World Athletics consensus. Athens makes the timing tricky. Buses for blocks 1 to 10 leave central Athens between 05:00 and 06:45, and buses for blocks 11 to 15 between 06:30 and 07:45. If you drive yourself, you must be at the venue by 07:30. Then you wait in Marathon, and you have no bag there. So many runners eat breakfast three to four hours before their block starts and need a planned top-up at the start.

• Three to four hours before your block: a practised meal such as bread or oats with honey, a banana, and a familiar drink, about 1 to 2 g of carbohydrate per kg.
• On the bus or at the start, 60 to 90 minutes before your block: a small low-fibre top-up you can carry, such as a cereal bar, a banana, or a sports drink.
• Ten to fifteen minutes before your block: an optional gel, only if used in training. You must be in your block 15 minutes before its start.
• Late blocks (09:45 to 10:09) may wait three hours after an early bus. Bring a second small snack, not just one.
• Keep caffeine at the dose and timing you know; race morning is not the day to double it.

Course tactics: the climb from km 11 to km 31

• Km 0 to 10: slight downhill for the first 4 km, a loop around the Tymvos burial mound to about km 6, then flat through Nea Makri. It is easy to run fast here. Hold back, and take your first gel about 20 minutes in.
• Km 11 to 20: the road rises in parts to km 17, drops steeply before the Rafina junction, then climbs again, steepest up to km 20. Keep effort, not pace, steady. Take the course gel or your own at the 20 km station.
• Km 20 to 31: Pikermi brings a mix of easier and harder climbing, with a long climb at km 25, more uphill through Pallini at km 27 to 28, then the hardest part of the route, the Stavros junction at km 30 to 31. The official GPX file puts the top roughly 240 m higher than the flat section near km 8. Eat before the steep parts, not on them.
• Km 31 to 37.5: a steep descent to Agia Paraskevi, then flat and downhill along Mesogeion Avenue through Chalandri and Cholargos, and a long downhill from the Ministry of National Defence to the Katechaki junction at 37.5 km. Shorten your stride and let the slope work. This is the easiest place to take a late gel.
• Km 37.5 to the finish: down Vasilissis Sofias, past the last station at Eleftherias Park (40 km), left onto Herodou Attikou at 41.2 km, and into the Panathenaic Stadium for the last 170 m on the track. Your last carbohydrate should already be in by about km 35.

The long-run rehearsal that makes the plan real

With three weeks to go, you have room for one full rehearsal and one shorter one. Pick a route with a long, steady climb in the second half, like the one from km 17 to km 31. Get up at your bus time, eat the same breakfast, wait as long as you will wait in Marathon, and start at your block time. Carry the same products and fuel at the same clock times. The goal is to learn whether you can still swallow a gel when you are breathing hard on a hill.

The shorter rehearsal is where you simplify. If gels on the climb are hard, move them to the station before each steep section and take them with water. If a gel every 20 minutes feels stressful, link your gels to the stations instead: every 2.5 km is about 11 to 28 minutes depending on pace, so a gel at every second station suits faster runners and a gel or half a gel at every station suits slower ones. The best plan is the one you can still follow at km 30.

Race-week Athens checklist

• Recheck the official race page for your final block time, drinks, and station list. Block times are only final two weeks before the race.
• Drop your bag at the expo at Faliro (4 to 7 November); you cannot drop one at the start.
• Check your bus time and boarding point for your wave, and plan breakfast and a start snack around it.
• Lay out every carried item, add one backup, and write grams and timing on one card. Mark the climb from km 20 to km 31.
• Note the cut-off clock times if you start in a late block or expect to finish in six hours or more.
• Check the forecast 48 hours out and adjust layers, fluid, and sodium, not the whole plan.
• Do not buy an unfamiliar gel at the expo because the flavour sounds good.
