Question 1

What makes Berlin the ideal PR course for nutrition?

Accepted Answer

Flat surface means consistent effort and predictable carb burn. Cool temperatures support GI function. Aid stations are well-spaced. It's the most controllable nutrition environment of any World Major.

Question 2

What gel timing works for Berlin?

Accepted Answer

Gel at miles 5, 10, 15, 19, and 22 — roughly every 35 minutes for a 3:30 runner. Course gels are at miles 13 and 20; carry your own for the first half and use course gels to supplement.

Question 3

How does racing for a PR affect my carb needs?

Accepted Answer

Faster pace = higher carb burn rate. A sub-3-hour runner burns 20–25% more carbs per hour than a 4-hour runner. Adjust your gel frequency up if you're racing hard.

Question 4

What is the most common Berlin fueling mistake?

Accepted Answer

Going out too fast in the first 10K because the course is flat and the atmosphere is electric. The first half of Berlin often runs 10–15 seconds per mile too fast, which drains glycogen before mile 20.

Question 5

Tips for the final 5K through Tiergarten?

Accepted Answer

If you've fueled correctly, Tiergarten is where you'll pass people. Take your last gel at mile 20 — don't wait until 23. The final 5K demands reserves you must have built through the whole race.
