An annual marathon that goes along the seaside of Oslofjord. It is very flat, and competitors in the marathon run it twice. There are four distances; marathon, half-marathon, 10 and 3 km.
First-hand event reviews from people who've been there, done that and got the breathable T-shirt, really help everyone choose their next event.
It only takes a few seconds and every month we randomly select someone who has taken the time to write a review and send them a £50 Wiggle voucher.
