How to choose your running race

Choose based on your level

Beginner? Start with a 5K or 10K. Regular runner? A half marathon is a great goal. Experienced? Marathon or trail, depending on your preference.

Allow enough training time

10K: 6-8 weeks. Half marathon: 10-12 weeks. Marathon: 14-16 weeks. Long trail: 16-20 weeks. Don't sign up too late.

Check the course profile

A flat course is faster but monotonous. A hilly course is harder but more scenic. Choose based on your goal (time vs. enjoyment).

Plan around the weather

Avoid summer marathons if you don't handle heat well. Spring and fall races offer the best conditions.

Register early

Major races (Boston, Chicago, NYC, Berlin) sell out months in advance or require a lottery or a qualifying time — Boston's April 19, 2027 race, for instance. Plan ahead.
