The Mediofondo is the 80 km distance of the Viana Granfondo 2027, starting and finishing in Viana do Castelo on 14 March 2027.

What this race demands

The 80 km ride demands sustained aerobic endurance and steady pacing. Elevation is not stated, so the amount of climbing cannot be assessed.

Aerobic endurance

Riding 80 km requires maintaining effort over a substantial distance, rather than relying only on short bursts of speed.

Steady pacing

Managing effort across the distance helps preserve the ability to keep riding strongly later in the event.

Climbing uncertainty

Elevation is not stated, so the climbing demand cannot be determined from the available facts.

For a ride likely to last around or beyond 2.5 hours, plan for roughly 60–90 g of carbohydrate per hour.
