The course, seen by a coach
Barcelona Marathon: what it asks of you, and how to train for it
"Flat and fast", with about 280 m of climbing
GPS data puts the gain near 280 m, much more than Seville or Valencia. It comes as long gentle drags, not hills. Do your goal-pace blocks on a route that rises and falls a little, and practise letting the pace drift 5 to 10 s/km on the way up while the effort stays the same.
The long Diagonal out-and-back
A long straight avenue out, a turn, and the same avenue back: it is a head game more than a leg one. Run some long runs on one long straight road and split it into chunks: next kilometre, next drink, next 5 km marker.
Declare an honest pace
Starts are staggered by the pace you declare. Overstate it and you spend 10 km being passed and pushed into a pace you cannot hold. Use the goal your training supports by February, not the one you typed in last summer.
Pace and plan by goal
Barcelona Marathon: pick your goal time
Each goal links to its pace chart: splits every 5 km, every kilometre and a printable pace band. Eight goals also have a free 16-week plan with paces worked out from your VMA. Pick the goal your recent half marathon supports, not the one you hope for.
When to start a 16-week plan
Start your 16-week plan on Monday, 23 November 2026
Race day is Sunday, 14 March 2027, in week 16. Started later, the plan loses build weeks, not the taper: cut from the start, never the end.

Even pace on a flat course. Hills, heat, wind and crowded first kilometres all cost time: the course notes above say where.
