Rennesøy Tempo is a 15.3 km cycling time trial on Rennesøy in Rogaland, held in August as part of a race series. Riders compete against the clock over a short course, with finish times and gaps to the fastest rider shown in the results.
The participants are local club racers from southwest Norway, including riders from Sandnes Sykleklubb, Rennesøy SK, Ryfylke SK, Tasta & omegn sykkelklubb, Dalane SK, Bryne CK, and Bogafjell Sykleklubb. Results are divided by bike category, gender, and age groups. Masters riders in their forties, fifties, and sixties compete alongside younger racers, and close finishes can be decided by mere seconds.
