What's actually happening at mile 20

The problem

Hydrogen ions — not lactic acid — build up as your muscles work hard. The rising acidity overwhelms your system. That's the wall

What BiCarb does

Sodium bicarbonate is alkaline. It neutralizes that acid buildup so your muscles can keep firing a little longer. Maurten's hydrogel delivery gets it there without wrecking your gut.

How to use it

Take BiCarb 90 minutes before your start time. That window matters — too early and the benefits fade, too late and you're still absorbing it when the gun goes off.
