Frequently Asked Questions

How long does it take to complete a half marathon as a beginner?

A beginner typically finishes a half marathon between 1h50 and 2h45, depending on initial fitness level. What matters is completing the race. Once you finish your first, you can progress to faster goals.

How do I manage nutrition during 21k?

For a half marathon, you'll need fueling during the race. Consume about 30-60g carbs per hour (gels, sports drinks, or dried fruit). Start fueling after 45 minutes. Always test your nutrition strategy on long runs!

Should I do cross-training or strength work?

Very beneficial! Add 1-2 light strength sessions (20-30 min) focused on legs, glutes, and core. Cross-training (swimming, cycling) once per week aids recovery and prevents injuries.
