## Frequently Asked Questions (FAQ)

### Q: What pace per mile is required for Jack Daniels VDOT Calculator vs Course-Graded Marathon Pace Band?
To achieve a 3h 11m 18s finish, your average target pace is 7:18 per mile. Under a 49.8% / 50.2% even-effort hill split plan, run the opening miles at 7:10/mi and cross the 13.1-mile halfway mark at 1h 35m 13s (unmasked above) before adjusting to 7:XX/mi across Crux Miles 16–21 (unlock exact Crux splits free via email above).

### Q: How many energy gels and grams of carbs do I need during the race?
Aim for 60g to 90g of carbs per hour for races over 2.5 hours. Using Maurten gels, take 1 gel 15 minutes before the start and follow your mile-by-mile fueling schedule at Mile 4, 8, 12, 16 (100mg Caffeine Gate), 19.5, and 22.5.

### Q: Why does running 3 to 6 seconds per mile slower in the first 5K prevent hitting the Mile 20 wall?
Going out 5% faster than 7:18/mi in the first 5K burns through stored muscle glycogen up to 24% faster. Holding 7:10/mi through Mile 3 and crossing 13.1 miles at 1h 35m 13s saves your legs for Crux Miles 16–21 and the final 10K push to 3h 11m 18s.
