With 154m of elevation gain, this is a moderately undulating course. The route ranges from 127m to 154m above sea level (27m total range). While not completely flat, the elevation changes are manageable for most runners and shouldn't significantly impact pacing strategy.

Expected Race Day Weather

Based on historical weather data for March, the expected race day conditions are as follows. Hot conditions are expected, with temperatures between 17°C and 28°C. Heat is one of the biggest performance factors in marathon running — research shows that for every degree above 15°C, marathon times slow by approximately 1-2%. Extra hydration and a conservative start are strongly recommended. There is a low chance of rain (8%), so dry conditions are likely.

Surface Type: Trail

Irving Marathon 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.
