Cycling & running events in Arendal, 2026

Arendal Training Notes

Running: Locals run the city centre, Hisøya, Tromøya, Hove, Granestua, Fossbekk, and the Arendal/Grimstad karuselløp loops. The Arendal/Grimstad karuselløp loop is 48 km and climbs 82 m, so it works for steady base miles or a sharper Z2 lap. Skagerrakmila anchors June with 10 km through the city centre and eastern outskirts. 4 km. Tromøy Ultra gives the longer crowd their day. Locals treat the races like club night, even when no named run club is on the brief.

Cycling: Arendal Cykleclub is the local hub, founded on February 14, 1975, with nearly 350 members and groups for women, men, youth, senior, and veteran riders. The club covers road cycling, mountain biking, and trail cycling, so the bunch can split into crit legs, gran fondo pace, cyclocross habits, or singletrack sessions. Herefoss Rundt is the anchor road tour, and Vårtråkken gives the time-trial crowd a target. Arendal - The long way around runs 49 km. Herefoss Rundt runs 90 km. The climbs come as the road leaves the coast, and locals know to spin, spin, spin.

Season: June, July, and August are the cleanest months for training in Arendal. Summer days stay sunny and mild, and daytime temperatures usually sit between 19°C and 24°C, which suits early intervals, evening Z2, and long rides over Hisøya and Tromøya. The coast keeps the feel fresh, but the wind can still bite from the side. Winter temperatures hover around 0°C, and easterlies can bring heavy snow before thaw turns it soft. Runners keep using trail and gravel when footing allows. Riders shift toward steadier roads, MTB, and trail cycling when conditions make sense.
