Common Questions & Answers

Frequently Asked Questions: Standard Even-Pace Wristband vs Hill-Adjusted Negative Split & Energy Gel Band

What pace per mile is required for Standard Even-Pace Wristband vs Hill-Adjusted Negative Split & Energy Gel Band?

To achieve a 3h 28m 57s finish, your average target pace is 7:58 per mile. Under a 49.9% / 50.1% even-effort hill split plan, run the opening miles at 8:07/mi and cross the 13.1-mile halfway mark at 1h 44m 17s (unmasked above) before adjusting to 8:XX/mi across Crux Miles 16–21 (unlock exact Crux splits free via email above).

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.

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 7:58/mi in the first 5K burns through stored muscle glycogen up to 24% faster. Holding 8:07/mi through Mile 3 and crossing 13.1 miles at 1h 44m 17s saves your legs for Crux Miles 16–21 and the final 10K push to 3h 28m 57s.

COACH TIP: HOW TO AVOID HITTING THE WALL AT MILE 20 Pacing Efficiency Benchmark

Avoid +8m 15s to +14m 40s Late-Race Slowdown Risk: Start Controlled and Fuel Early (72g Carbs/Hr + 49.9% / 50.1% Split)

Going out 10-15 sec/mi too fast in Miles 1-5 burns through your energy stores 38% faster and can cost you 14+ minutes after Mile 20. Your Rolling / Hill Adjusted (+/- 450ft GAP) pace plan hits halfway at 1h 44m 17s and finishes strong in 1h 44m 40s on the second half with 11 timed gels (72g carbs/hr).
