How to Choose Your First Marathon

Now that you’ve seen 10 excellent options, how do you actually choose? Consider these factors:

1. Geography and Travel

Do you want to stay local or make it a destination race? Local races save money and reduce pre-race stress. Destination races turn your first marathon into a vacation but require more planning.

2. Time of Year

When does your training timeline work best? Spring marathons (March-May) mean winter training. Fall marathons (September-November) mean summer training. Choose based on what works with your schedule and climate.

3. Course Difficulty

Be honest about your training environment. If you train in a flat area, don’t choose a hilly first marathon. If you regularly train on hills, flat courses will feel easier.

4. Goals

Are you running for time or experience? If you want to finish as fast as possible, choose a flat, fast course like Chicago or Mesa. If you want an unforgettable experience regardless of time, consider Disney or Big Sur.

5. Budget

Entry fees range from $100-$225, but add in travel, lodging, and meals. Local races are most budget-friendly. Destination marathons can cost $1,000+ when everything is included.

After You Choose: Register and Start Training

Once you’ve selected your first marathon:

1. Register immediately (popular races fill up or use lottery systems)
2. Find a training plan that matches your experience level (12-20 weeks typical)
3. Book travel and lodging if it’s a destination race
4. Start logging your training to track progress and stay accountable
5. Join a running group or find a training partner for motivation
