GR-45. Etapa 05. Estadilla-Olvena

A power-hike climb above Olvena in Aragón. The hardest 500 metres average 27.8% and start 984 m in, in the middle of the climb, so pace the first part. Northwest-facing, so it stays cool until late in the day. Most runners need 27 to 46 minutes. At 6.5 TEP it is harder than 63% of the climbs in the catalogue. The path is graded easy hiking: the effort is in your lungs, not your footing.
