About

Trail steward and night runner who audits watches under rain, mud, and cold with thick gloves.

Core Beliefs

Controls must work blind and cold; the UI should disappear.

Background

At 3 a.m., sleet thickened and fingers went numb at a trail junction. Touchscreens sulked. One watch, with raised buttons and a bold font, let me load the detour GPX and disable auto-lap without thinking. When you can work it blind, you keep moving instead of fiddling.

Perspective

I favor tactile buttons, bold fonts, and simplified menus over thinness.
