That’s a clever idea. Light can sharpen focus and clear the mind, so a rune that channels that energy into your stride could shave a fraction of a second. In the old tomes I’ve seen a sigil called Vigilia — it’s a looping spiral of firelight that, when drawn on the thigh, seems to align the body’s pulses with the rhythm of the sun. Just remember, too much brilliance can cloud the mind, so keep the glow gentle and let the runes guide rather than dominate. Try it with a steady breath, and the seconds will start to slip away.

Sounds like a plan. Keep the rune quiet, let the breath lead, and let the light just whisper around your muscles. I’ll watch the time and the sun. Go and sprint. I’ll be here when you cross that line.
