Gravel is the most varied group here. The Riverside Gravel Intro is 34 km with 250 m of climbing on wide tracks, so it suits riders new to unpaved surfaces. The Forest Gravel Loop steps up to 72 km and 1,050 m through pine forest and quiet farm roads east of the city, a full day that needs a decent base of fitness. The Volcano Gravel Day is the toughest at 88 km and 1,600 m between extinct volcanoes and beech forest. Choose the intro to learn bike handling, the forest loop for a solid day out, and the volcano day if you already ride long hours with steady climbing.
