The Reykjavík Marathon (August) runs during the midnight sun, with the race starting at 10pm and finishing in low-light conditions—a surreal, bucket-list experience. This 8-day trip combines the flat, spectator-rich urban race with Iceland's Golden Circle day trips, geothermal spa recovery (Blue Lagoon, Sky Lagoon), and potential Aurora viewing.
