Prague, Czech Republic · Tuesday 4 May 2027
The ORLEN Prague Marathon takes place in May 2025 on a trail surface through Prague, Czechia, covering the full 42.2 kilometre distance with gently rolling terrain and minimal elevation change that keeps the course relatively forgiving. This is a RunCzech organized event, part of an established running series that caters to both competitive racers and recreational runners, with extensive support infrastructure including live streaming and a mobile app for tracking. The flat to rolling nature of the course makes it suitable for runners of varying abilities, though the trail surface means you'll want to prepare your feet and legs accordingly rather than assuming road-running fitness will translate directly. Registration transfer is available if your plans change, and the race sits within a broader ecosystem of running communities and events, so you'll have access to RunCzech's support systems before and after race day. Given that this is a spring marathon in a central European city, weather conditions should be mild, making it a realistic target for solid training and execution.
