An almost flat city course, from Passeig de Picasso to the seafront
The course is almost flat: the map published by the organizer (the 2026 edition's, the latest online) shows 71 m (233 ft) of total climbing, 37 m (121 ft) in the first 6.2 miles and 34 m (112 ft) after that, with 25 turns and a longest straight of 1.6 miles. The start is on Passeig de Picasso, alongside Ciutadella park; the finish is nearby, on Passeig de Pujades.
The route passes the Columbus monument, Avinguda del Paral·lel, Gran Via (miles 2.5 to 4.3), the Arc de Triomf, Pallars and Perú streets, Avinguda Diagonal and the Parc del Fòrum (around mile 10.6), before heading back along Avinguda del Litoral, by the sea. The organizer describes it as a fully urban circuit through the heart and along the coast of the city. Time limit: 2 h 45 after the last runner crosses the start line.
The three key workouts for an almost flat half
On an almost flat half, what counts is half-marathon pace held for a long time, all the way back along the seafront. Here are the three key workouts in the Running Workout plan; your assistant builds them at your paces and sends them to your watch.
- Threshold (week 4, New Year's week): 3 × 10 minutes at threshold pace, 2 minutes recovery. The groundwork that holds through the holidays.
- Half-marathon pace in long blocks (week 8): 2 × 3.1 miles at half-marathon pace, 3 minutes recovery; each block is twice the course's longest straight.
- Long run with a fast finish (week 8): 1 h 48 with the last 28 minutes at half-marathon pace, to hold pace late in the race, on Avinguda del Litoral.
A training block that runs through the holidays and January
The plan runs from December 7 to February 14: Christmas falls at the end of the base phase (week 3), New Year's and Epiphany (Wednesday, January 6) during the build (weeks 4 and 5), and the half-marathon-pace block starts on January 18, followed by a taper week. So the holidays come before the decisive block, and January brings cold sessions, early in the morning or after dark.
A lighter week over the holidays? Your assistant reads your Garmin activities, reviews the week and adjusts the next one, without catching up. If you go away, log it as a constraint (available days, terrain): it takes it into account when placing your workouts and sends them to your watch.
Bibs and race day
The 37th edition is sold out: all 40,000 bibs went in seven days, the organizer says. The start is at 8:30 a.m. (wheelchairs at 8:25 a.m.), from colored corrals matching your bib, with the race expected to end around 1:15 p.m.; 30 pacers cover ten target times, from 1:20 to 2:05. After the finish, your assistant analyzes your watch's activity: pace by section, evenness on the Diagonal and the Litoral, heart rate.
