Marathon runners are a hardy breed. They love running, all the way up to 26.2 miles. They typically train hard, and there's not much that will stand in the way of preparing for their next marathon. We've compiled this list to help keep that spirit alive. Check out the races listed below, and keep on running!

Spring 2025: April - May

Spring offers a fantastic mix of marathon opportunities, with generally moderate temperatures in many areas. However, it's crucial to be prepared for the variability the season can bring.

Spring Marathon Tips:

  • Weather Awareness: Spring weather can be highly variable. Be prepared for anything from cool mornings to warmer afternoons, and potential rain. Layered clothing is crucial, allowing you to adjust your outfit as needed.

  • Allergy Management: Spring is also allergy season. If you are prone to allergies, take necessary precautions before and during the race, such as taking medication and monitoring pollen levels.

  • Hydration: As temperatures gradually rise, it's essential to stay well-hydrated. Pay attention to your fluid intake in the days leading up to the race and consider carrying a hydration pack for easy access to water or electrolytes.
