Valencia, Spain · Saturday 30 May 2026
This race works well for runners who want a full marathon experience without the mountainous terrain that demands serious hill training. The flat to gently rolling course means you can focus on pacing and endurance rather than managing dramatic elevation changes. Trail runners will appreciate the surface variety, and those training for road marathons elsewhere can use this as a solid fitness test on slightly different footing. It suits runners targeting a honest time trial in late May when fitness tends to peak, and anyone wanting to explore Valencia as part of their racing calendar will find a well-organised event with decent infrastructure around registration and support. The main challenge is the trail surface itself. Running 42 kilometres on dirt or packed earth demands more from your stabiliser muscles and feet than road running, so even fit runners often find their legs feel heavier than expected. You'll need proper trail shoes with adequate grip and support, and training some of your long runs on similar surfaces beforehand makes a real difference. The course's gentle rolling nature means there's no obvious climb to fear, but those constant small undulations can accumulate fatigue faster than a genuinely flat road marathon. May heat in Valencia is also worth factoring in, especially if the race day conditions turn warm. The event website doesn't provide detailed course description or aid station specifics from the scraped content, so you'll want to contact organisers directly about water stops and nutrition support on the trail sections.

Extra hydration and a conservative start are strongly recommended. There is a low chance of rain (0%), so dry conditions are likely.
Valencia Marathon Trinidad Alfonso EDP is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
