Barcelona Half Marathon 2027 fueling guide: aid stations, the Finisher gel, the 8:30 start, and a plan for your pace

The Barcelona Half Marathon is on Sunday, February 14, 2027, with an 8:30 a.m. start on Passeig de Picasso, next to Parc de la Ciutadella. The 2027 regulation lists liquid aid stations at about km 5, 10, 15, and 17.5 (about 3.1, 6.2, 9.3, and 10.9 miles). The official FAQ says each one has water and Aquarius in cups, and the km 15 station also hands out Finisher gels. That is one course gel and four cup stations. For most runners, that covers fluid but not fuel, so carry one to four gels of your own and treat the km 15 gel as a planned dose only if you have tested it.

The race now runs as the Hyundai Mitja Marató Barcelona by Brooks; the old eDreams Mitja Marató Barcelona web address redirects to the current site. The course is an urban loop through the Eixample, Poblenou, and along the sea, and the official course map shows only 71 m (233 ft) of climbing in total, which is why it is known as a fast, flat course. This guide covers what the organizer has published, when you will reach each station at your pace, three fueling plans, and what to eat before an 8:30 start. The only course map online is still the last edition’s (February 15, 2026), so recheck the route and stations when the 2027 race-week information comes out.

Barcelona Half Marathon 2027: the confirmed race facts

The regulation does not mention carried bottles, belts, or help from friends on the course. Most runners carry gels in a belt or pocket, and that is the safest way to have your own fuel. If you want to carry a bottle, check the race-week information first.

Barcelona Half Marathon aid stations: what is at each one

The station kilometres below come from the 2027 regulation and the station contents from the 2027 FAQ. Locations are read from the last edition’s official course map and are approximate.

One detail is unclear. The 2027 FAQ names only the km 15 station for Finisher gels, while the last edition’s official course map also showed the gel symbol at km 10 and km 17.5. Plan around km 15 and treat any gel at the other stations as a bonus. Finisher is the sports nutrition brand of Kern Pharma. The organizer has not said which gel it will hand out or how much carbohydrate it has. If you want to use it, buy the same product before race week, test it in a long run, and read the sachet. Otherwise carry your own and take only water at km 15.

Aquarius in Spain is a light drink, not a full sports drink. Coca-Cola España lists Aquarius lemon at 4.4 g of carbohydrate and 0.05 g of salt (about 20 mg of sodium) per 100 ml, and it is sweetened partly with sucralose and acesulfame K. A cup of 100 to 150 ml gives about 4 to 7 g of carbohydrate and 20 to 30 mg of sodium. Four cups add up to roughly one small gel. Count it as a top-up, not as your fuel.

When you will reach each aid station at your pace

The table shows elapsed time at each station for an even pace, from when you cross the start mat. With staggered starts, your clock time will be later than the 8:30 gun if you start in a later box. A 1:30 runner reaches the km 15 gel after about an hour. A 2:45 runner gets there just before two hours, and runs more than 35 minutes between each station.

The 2:45 column is the time limit pace. The limit runs from when the last runner crosses the start line, so starting in a late box does not shorten your time. Runners aiming for 2:30 or slower should still keep some margin, because the stations are where most people lose time.

Pick your plan: three runner profiles

The World Athletics consensus on distance running and the ACSM position stand both give 30 to 60 g of carbohydrate per hour for events of about one to two and a half hours. For efforts of roughly 45 to 75 minutes, they suggest small amounts or a sports drink mouth rinse. Intakes above 60 g per hour belong to longer races and need a glucose plus fructose product and a trained gut. With 25 g gels, one every 30 minutes gives 50 g per hour, and one every 25 minutes gives 60 g. In Barcelona the stations are 5 km apart, so it is simplest to take each gel a few minutes before a station and wash it down with water there.

Racing it: your race is short, so the job is to start full and top up. A 1:30 runner at 40 g per hour needs about 60 g in the race. That is a gel 10 to 15 minutes before the start, one at about 40 minutes with water at km 10, and either the course gel at km 15 (about 1:04) or a few cups of Aquarius. Do not take an untested gel at race pace. If you are not sure about Finisher, carry your own second gel instead.

Steady half: think in grams. A 2:00 race at 55 g per hour is about 110 g. Aquarius at all four stations adds roughly 20 to 25 g. Three carried 25 g gels add 75 g, taken just before km 5 (0:28), km 10 (0:57), and km 15 (1:25). If you take the course gel at km 15 instead of your own, keep the third carried gel for km 17.5 (1:40) or skip it if you feel good. At 2:15, take all three plus a half gel at 17.5.

Long day: two and a half hours changes the math. Fifty grams per hour over 2:30 is 125 g. Aquarius at four stations gives about 25 g, so carry four gels: one just before km 5 (0:36), one at km 10 (1:11), one at km 15 (1:47), and one at km 17.5 (2:04). Add the course gel only if you have tested it and want more. You will run 35 minutes or more between stations, so a small handheld bottle or soft flask lets you take gels with water when you need them. Small, frequent doses are kinder to the stomach.

Caffeine, sodium, and the km 15 gel

• 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. The organizer has not said whether the course gel contains caffeine, so read the sachet before you take it and count it with any coffee and caffeinated gels.
• An 8:30 start makes timing easy: coffee with breakfast around 6:00 is a little early, so a practised caffeinated gel 30 to 45 minutes before your box starts is a simple way to have caffeine on board.
• Sodium: Aquarius gives only about 20 to 30 mg per cup. In a cool February half that is fine for nearly everyone. Heavy, salty sweaters on a warm, sunny day may want a tested salt product as well.
• At km 15: grab one gel, keep moving, and drink water at the same station. Squeeze it in two or three goes rather than all at once.
• Tear the top of your own gel a minute before a station, so you can drink with the same hand.

Hydration for a February morning in Barcelona

AEMET normals for Barcelona Airport give a February average high of 14.3 °C (58 °F) and an average low of 5.4 °C (42 °F), with humidity around 70 percent and about four days with 1 mm of rain or more in the month. Sunrise on February 14 is at about 7:50 a.m., so the 8:30 start comes in cool morning air, and a 2:00 runner finishes around 10:30 to 11:00 depending on their box. From about km 17 to km 20 the course runs along the sea, where sun and wind can change how it feels. In cool weather, sweat losses over a half are modest. Drink to thirst, and do not finish heavier than you started: World Athletics warns against drinking more than you sweat.

• There are only four stations, about 5 km apart, and 3.6 km (2.2 miles) from km 17.5 to the finish. Runners who like to sip often should carry a small bottle.
• Expect to wait in your start box in the cold. Bring an old layer you are happy to leave behind, and keep your gels warm.
• Rain is not common in February, but a wet start makes gels slippery to open. Practise tearing them with cold hands.
• Ask for help at a medical point for confusion, severe headache, repeated vomiting, or collapse; the FAQ says every station has one.

Breakfast for an 8:30 start

A familiar carbohydrate-rich meal one to four hours before racing is the standard advice in both the World Athletics consensus and the ACSM position stand. With an 8:30 gun and staggered starts after it, most runners can eat at about 5:30 to 6:30 a.m. in their hotel or at home. The organizer has not yet published the 2027 box opening times or race-morning transport, so plan your breakfast around the time you must leave, not the time you start.

• Two to three hours before your start: a practised meal such as white toast or a bagel with jam or honey, a banana, and a familiar drink, about 1 to 2 g of carbohydrate per kg.
• Sixty to ninety minutes before: a small low-fibre top-up, such as a banana, a few plain biscuits, or a sports drink.
• Ten to fifteen minutes before your box starts: an optional gel, only if used in training.
• Keep caffeine at the dose and timing you know; race morning is not the day to double it.
• The day before, eat normal meals with extra carbohydrate. A half does not need a full marathon carb load; see our half marathon carb-loading guide.

Course tactics: a fast, flat course from the Ciutadella to the sea

The last edition’s official course map lists 37 m (121 ft) of climbing from 0 to 10 km and 34 m (112 ft) from 10 km to the finish, 71 m (233 ft) in total, with 25 corners and a longest straight of 2.54 km (1.6 miles). The elevation profile stays close to sea level the whole way. The route below is read from that map and is approximate until the 2027 map is published.

• Km 0 to 3: from Passeig de Picasso along Passeig d’Isabel II to the Columbus monument, then up Avinguda del Paral·lel and Ronda de Sant Pau. The start is crowded; settle into pace and take nothing but your pre-start gel.
• Km 3 to 7: along Carrer de Sepúlveda to Carrer d’Entença, then east on the long, straight Gran Via de les Corts Catalanes, with the first station at km 5, then down Carrer de Bailén to the Arc de Triomf. Take your first carried gel a few minutes before km 5.
• Km 7 to 13: Passeig de Lluís Companys, Passeig de Pujades, and Carrer de Pallars into Poblenou, then north on Carrer de la Llacuna to the km 10 station, east on Carrer del Perú, and back south on Rambla de Prim. This is the main eating window for steady runners.
• Km 13 to 17: two passes along Avinguda Diagonal, with the km 15 gel station on Carrer de Pallars between them. Take your gel just before the station and drink water there.
• Km 17 to 21.1: down to the sea at Parc del Fòrum, the last station at km 17.5 on Passeig de García Fària, west on Avinguda del Litoral past the Hotel Arts, then north on Carrer de la Marina to the finish on Passeig de Pujades. Run this on fuel already taken; a cup at 17.5 is the last top-up.

The long-run rehearsal that makes the plan real

With about fifteen weeks to go, you have time to practise properly. In January, do at least two runs of 16 to 21 km (10 to 13 miles) that start at 8:30 a.m., after the same breakfast you will eat at 5:30 to 6:30, carrying the same gels and taking them at the same elapsed times as in the table above. If you plan to use the Finisher gel at km 15, buy the same product and test it here, at race effort, about 75 to 90 minutes into the run.

The second rehearsal is where you simplify. If carrying four gels is awkward, try chews, or a small bottle with a carbohydrate drink. If a gel every 25 minutes feels stressful, link your gels to the course instead: one just before each station. The best plan is the one you can still follow on Avinguda Diagonal at km 14.

Race-week Barcelona Half checklist

• Read the race-week information when it is posted: confirm the station kilometres, which stations hand out Finisher gels, which gel it is, and your box start time.
• Collect your own bib at Expo Sports: Thursday 15:00 to 20:00, Friday and Saturday 9:00 to 20:00. Bibs are not handed out on race day, and someone else can only collect yours with your authorization and ID.
• Fill in the back of your bib with your emergency contact and any medical information; the regulation requires it.
• Lay out every carried item, add one backup gel, and write grams and timing on one card.
• Check the forecast 48 hours out and adjust layers, fluid, and sodium, not the whole plan.
• Do not switch to a new gel at the expo because the flavour sounds good.
