The Flattest Half Marathons in Europe (Perfect for a PB)

The Flattest Half Marathons in Europe (Perfect for a PB)

Jordanna Vyse |

If you’re chasing a personal best, course profile matters. A lot.

Flat half marathons remove one of the biggest performance variables: elevation. No climbs, no rhythm-breaking descents - just pure, uninterrupted running. Whether you’re targeting a sub-90, sub-2, or simply your fastest ever race, Europe is packed with pancake-flat courses built for speed.

Here’s our pick of the flattest half marathons in Europe worth adding to your race calendar.

 

Malaga Half Marathon (Spain)

Arguably the flattest half marathon in Europe right now.

The Malaga course is famously fast, with just ~6 metres of elevation gain across the entire race . That’s about as close to perfectly flat as you’ll find anywhere.

  • 🏁 Elevation: ~6m total gain
  • 🌊 Route: Coastal, wide roads
  • 🎯 Best for: Serious PB attempts

If you want zero excuses and maximum speed potential, this is the one.

 

Copenhagen Half Marathon (Denmark)

Part of the SuperHalfs series, Copenhagen is known for being extremely flat and fast, with less than 16 metres elevation gain .

  • 🏁 Elevation: <16m
  • 🏙️ Route: Smooth city roads
  • ⚡ Bonus: Elite-level pacing groups

This is one of Europe’s premier PB courses—fast, well-organised, and stacked with strong runners.

 

Seville Half Marathon (Spain)

Seville has long been considered one of the flattest races in Europe, with wide boulevards and minimal elevation changes .
  • 🏁 Elevation: Minimal
  • ☀️ Conditions: Mild winter weather
  • 🏃♂️ Feel: Fast, open roads

It’s a favourite for runners chasing early-season PBs.

 

Lisbon Half Marathon (Portugal)

One of the most iconic races in Europe—and famously flat and fast .
  • 🏁 Elevation: Flat profile
  • 🌉 Highlight: Bridge start
  • 🎯 Best for: Big race atmosphere + PB

It’s also part of the SuperHalfs series, so ideal if you’re ticking off major races.


Berlin Half Marathon (Germany)

Berlin is synonymous with speed. The half marathon follows suit with a flat, fast course perfect for PBs .

  • 🏁 Elevation: Very flat
  • 🏙️ Route: Wide, straight roads

Barcelona is another standout, with a course designed for speed and minimal elevation changes .

Lille Half Marathon (France)

Less hyped, but seriously quick.

With under 100m elevation gain, Lille is considered a flat, fast course that attracts elite times .

  • 🏁 Elevation: ~98m
  • 🏃♀️ Field: Strong competitive runners
  • 🎯 Best for: Low-key PB attempt

What Makes a Half Marathon “Fast”?

If you’re choosing your next race, look for:

  • Low elevation gain (ideally under 50m total)
  • Wide roads and few sharp turns
  • Cool weather conditions
  • Strong pacing groups or elite fields

Flat doesn’t guarantee a PB - but it gives you the best possible shot.
