Two weeks to arrive fresh
A city course with a little climbing
Since 2024 the race has started on Passeig de Gràcia. In 2025 the route passed the Sagrada Família, the Columbus Monument, Parc de la Ciutadella and the seafront out to the Fòrum, finishing at the Arc de Triomf: about 440 ft (134 m) of total climb, some 250 ft of it in the first half, and a 2.9-mile straight on Carrer de València, from mile 3 to mile 6.
Nothing steep, but the climbing is spread over the whole course, slightly more of it in the first half. Check the 2027 route on the official website (map, GPX file) before settling your race plan.
Winter preparation, spring race
Mid-March: a 16-week plan from late November, or 12 weeks from late December. January and February carry the load in the cold; March brings the taper and the first runs in light kit.
The AI coach reads your actual sessions every week on Garmin. It checks that the training load climbs without excess and brings an assimilation week forward if how you feel deteriorates two weeks running.
Pacing: do not let the crowd carry you away
The 2026 edition sold out with 32,000 entrants, and starts go in waves by the pace given at registration. The rule: first two miles at target pace plus 15 seconds per mile, then target pace, accepting a few seconds lost on the climbs without trying to win them back straight away.
- Late November to December: volume, long run up to 2 h.
- January-February: marathon-pace blocks, long runs up to 2 h 30 finishing at marathon pace.
- March: taper, fresh legs for the 14th.
The watch, with its pace range per segment, is your guardrail at the start. What you do not waste at mile 3, you get back at mile 22.

The organizer calls it flat and fast; the 2025 route had about 440 ft (134 m) of total climb, spread over the whole course. A fast time is possible with well-managed pacing, not by going out fast.
