Prague Marathon 2027 fueling guide: refreshment stations, cobblestones, and a plan for every finish time

The Prague Marathon starts at 08:00 on Sunday, 2 May 2027, on Old Town Square, and the last edition gave runners 16 station passes: eight water points with Mattoni water and eight refreshment points that added Gatorade isotonic drink, bananas, oranges, salt and sugar. There were no gels on the course list. So the course gives you fluid and some sugar, but the carbohydrate plan has to come with you from the start. This guide sets out what RunCzech has published, when you will reach each station at your pace, and three plans to choose from.

Three things make Prague different. The 08:00 start means breakfast in the dark for most hotel guests. The course is flat, but about 3.8 km of it is cobbled, including Charles Bridge, and it has two out-and-back turns where stations are shared in both directions. And the race changed title partner: what many runners still call the ORLEN Prague Marathon has been the Vodafone Prague Marathon since the last edition. The 2027 map is not out yet, so the station details below are based on the last edition’s official map and runner information. Recheck them in race week. Running the half in April? The Prague Half Marathon fueling guide covers that race.

Prague Marathon 2027: the confirmed race facts

The cut-offs are clock times counted from the 08:00 gun, not from when you cross the line. Your official result is your net time, but the limit is not. If you start from a back corridor, the minutes you spend walking to the line come out of your margin. The table shows last edition’s cut-offs; the 2027 times will be on the new map.

What is on the Prague Marathon course

This is the full list from the last edition’s official runner information and course map. In Czech, a refreshment point is an občerstvovací stanice (občerstvení means refreshments) and a water point is an osvěžovací stanice. Four sites are passed twice, once on the way out and once on the way back, which is why 12 sites give 16 passes.

Stations come about every 2 to 3 km, so fluid is never far away. Carbohydrate is a different story. Gatorade appears only at the eight refreshment points, and the two longest gaps are 10.4 to 15.9 km and 30.5 to 36.2 km. The second gap falls at the point of a marathon where most runners start to fade. Plan a carried gel inside each gap.

RunCzech lists Gatorade isotonic drink but does not publish its carbohydrate content, and we could not confirm the European label on Gatorade’s own site, so check the bottle at the expo. For scale, Gatorade Endurance Formula has 22 g of carbohydrate per 12 oz (355 ml), about 6 g per 100 ml. At a similar strength, a cup of 100 to 150 ml gives roughly 6 to 9 g, less what you spill. Eight cups add up to about 50 to 75 g over the whole race, about one hour of fuel for most runners. Count it as a top-up, not your plan. Bananas, oranges and sugar help at a walk, but they are hard to eat at race pace. RunCzech also asks runners to use the full length of each station, not just the first table, and to drop cups and gel wrappers only in the marked drop zones.

When you will reach each station at your pace

The table shows elapsed time from your own start at an even pace, using last edition’s station positions. A 3:00 runner reaches the halfway refreshment point at 1:30, or 09:30 on the clock. A 6:00 runner reaches it at 3:00 and the Jateční refreshment point at 36.2 km after 5:09, a little after 13:10 on the clock if they crossed the line a few minutes after the gun.

Pick your plan: three runner profiles

World Athletics’ consensus statement gives 30 to 60 g of carbohydrate per hour as the usual marathon range, and its companion paper on distance runners suggests trained runners try up to 90 g per hour in events longer than about 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 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 volume. At 75 g per hour from gels alone, a 3:00 race needs nine 25 g gels, and none can come from the course. Gatorade at race pace is often half spilled, so count only a few grams per cup. Build your number over eight to ten weeks of long runs, starting at 60 g and adding 10 to 15 g every second week while your stomach stays quiet. Take the first gel at 20 to 30 minutes, at the 6.8 km refreshment point, then one about every 20 minutes, timed to the nearest station so you always have water. The last one should go in near 33.5 km, so it has time to work before Karlín.

Steady marathon: think in grams. A 4:00 race at 60 g per hour is 240 g. Eight cups of Gatorade cover perhaps 50 to 75 g of that, if you drink most of each cup. That leaves about seven carried 25 g gels, roughly one every 25 to 30 minutes. At 4:00 pace, stations come every 10 to 18 minutes, so you can pair every second station with a gel. Put one gel at the 13.5 km water point and one at the 33.5 km water point, inside the two long Gatorade gaps. Write the grams next to each item and total each hour.

Long day: five to seven hours on your feet changes the math. Fifty grams per hour over six hours is 300 g, and the course covers only part of it, even if you eat bananas, oranges and sugar at every refreshment point. Small, frequent doses work best: a gel every 30 minutes, or half a gel every 15, with a piece of banana or a cup of Gatorade when a gel feels like too much. Watch the clock too. A 6:30 runner who crosses the line a few minutes after the gun reaches 21 km at about 3:20 on the clock, against a cut-off of 3:33. Eating on schedule in the first three hours is what keeps you ahead of the cut-offs after the Strakonická turn.

Caffeine, sodium, and the things runners forget

• Caffeine: the ISSN position stand supports 3 to 6 mg per kg taken about 60 minutes before exercise. For a 70 kg runner, 3 mg per kg is 210 mg. With an 08:00 start, that means around 07:00, before you walk into the line-up on Celetná. Count coffee, pre-race products and caffeinated gels together.
• No caffeine on the course list: last edition’s stations listed no cola or caffeinated gels, so any caffeine you want late in the race has to be carried and tested.
• Sodium: the refreshment points offer salt, and Gatorade adds a little. In a cool May race most runners need nothing more, but heavy, salty sweaters can carry a salt product they have tested in long runs.
• Gels: bring every gel you need plus one spare, in a brand you have trained with. None were on last edition’s course list.
• Wrappers: tear the top before a station, and keep the empty wrapper until the next marked drop zone. Throwing packaging outside the zones is not allowed.
• Cobbles: do not try to open a gel on Charles Bridge or Dvořákovo nábřeží. Take it on smooth asphalt and keep your eyes on the ground.

Hydration for an early-May morning in Prague

On 1 May, Prague averages a daily high near 17 °C (62 °F) and a low near 7 °C (44 °F), with about a 23 percent chance of a wet day and almost no muggy days. Most of the race runs in the cooler morning hours, but the last runners are out until about 15:00, so slower runners finish in the warmest part of the day. Last edition had sprinklers at every station except 33.5 km, where a misting vehicle stood instead, plus sprinklers in the middle of Pařížská, at 12.6 km, and beyond the finish. 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 in March and April.
• Pick your priority stations now. Sixteen stations do not need sixteen decisions at race pace.
• RunCzech suggests dressing as if it were 5 °C warmer than the forecast. Old layers left at the start go to people in need.
• Toilets were at every refreshment point last edition, which helps if a cold start sends you looking for one early.
• Seek help at a first-aid point for confusion, severe headache, repeated vomiting, or collapse, whatever the clock says. In the Czech Republic the ambulance number is 155.

Breakfast for an 08:00 start

A familiar carbohydrate-rich meal one to four hours before racing is the standard framework, and ACSM gives 1 to 4 g of carbohydrate per kg in that window. With an 08:00 start, most runners will use the lower part of that range, about 2.5 to 3 hours before. Last edition, the technical area on the lower part of Wenceslas Square opened at 06:00, the line-up on Celetná opened at 07:30, and the gun went at 08:00 on Old Town Square. If you stay in a hotel, check when breakfast opens; if it is after 05:30, bring your own.

• 05:00 to 05:30, about 2.5 to 3 hours before: a practised breakfast such as white bread or a bagel with jam or honey, rice, a banana and juice, about 1 to 2 g of carbohydrate per kg. Keep fat and fibre low.
• 06:00 to 07:00: sip water or a sports drink you know while you get to the technical area and drop your bag.
• Around 07:00: caffeine, at the dose and timing you have practised.
• 07:30: line up in your corridor on Celetná.
• 07:45 to 07:50: an optional gel, only if used in training. The first refreshment point is not until 6.8 km.
• Your bib was not a public transport ticket last edition, so buy one in advance if you take the metro to Můstek or Staroměstská.

Course tactics: where Prague tempts you

The 2027 course has not been published yet. These notes follow last edition’s official map and course description. The elevation profile on the map is close to flat; the challenges are the cobbles, the corners and two turnarounds.

• 0 to 4 km: Old Town Square, Pařížská, the Čechův bridge, then Klárov, Malostranské náměstí, Mostecká and Charles Bridge at about 2.8 km. About 1.2 km of this opening section is cobbled. The crowd and the sights pull you along; hold back and run smooth.
• 4 to 12 km: along the river to Holešovice, over the Libeň bridge, through Karlín past the Lilith sculpture at 9.3 km and down Rohanské nábřeží. Refreshment points at 6.8 and 10.4 km. Take your first gel here, on asphalt.
• 12 to 21 km: 710 m of cobbles on Dvořákovo nábřeží, back through Old Town Square at 12.7 km, Celetná, Na Příkopě and Wenceslas Square, then the National Theatre, the Dancing House and the Jiráskův bridge. Gatorade at 15.9 km on Zborovská and at halfway on Podolské nábřeží. This is the calm middle of the race; keep eating on the clock.
• 21 to 31 km: the first turnaround past Vyšehrad at about 22 km, back through the Vyšehrad tunnel, over the Palackého bridge to Svornosti at 26.2 km, then the second turnaround on Strakonická near 28.5 km. Shorten your stride and slow down into each turn. Gatorade at 30.5 km on Nábřežní.
• 31 to 42.2 km: the Legion bridge, the National Theatre and Rudolfinum again, water and mist at 33.5 km, back to Holešovice for Gatorade at 36.2 km, and Karlín once more. The last 710 m of cobbles on Dvořákovo nábřeží come near 41 km. Your last carbohydrate should be in by about 37 to 38 km.

The long-run rehearsal that makes the plan real

Prague asks you to race early, so in March and April schedule two or three long runs that start at 08:00. Eat breakfast at 05:00 to 05:30 as on race day, carry the same products, and fuel at the same clock times. If you plan to drink Gatorade from the course, buy the isotonic version and test it in these runs. Include a few kilometres on cobbles or rough paths, and practise taking a gel and a cup on a stretch where you have to watch your footing.

The later rehearsals are where you simplify. If carrying eight gels is awkward, lean on the eight Gatorade stops and carry gels mainly for the two long gaps. If a gel every 20 minutes feels stressful, link your gels to the stations instead: they come every 2 to 3 km. The best plan is the one you can still follow on Rohanské nábřeží at 38 km.

Race-week Prague checklist

• Recheck the 2027 map and runner information for station kilometres, drinks, cut-offs and the start schedule as soon as RunCzech publishes them.
• Note your corridor on your bib, and remember the cut-offs count from the gun, not from when you cross the line.
• Lay out every carried item, add one backup, and write grams and timing on one card. Mark the 10.4 to 15.9 km and 30.5 to 36.2 km Gatorade gaps.
• Plan your morning backward from 08:00: breakfast, caffeine, bag drop at the technical area, line-up at 07:30.
• Check the forecast 48 hours out and adjust clothing, fluid and sodium, not the whole plan.
• Do not buy an unfamiliar gel at the expo because the flavour sounds good.
