The Miodet originates at 1,000 metres (3,300 ft) above sea level, at Saint-Éloy-la-Glacière, near the Bois de Mauchet, elevation 1,095 metres (3,593 ft).

It first runs south, before turning north-west at le sommet du Grun du Bois, elevation 896 metres (2,940 ft).

It is joined by le ruisseau des Martinanches at Saint-Dier-d'Auvergne, then veers north-east.

It runs north shortly before its confluence with the Dore on the left bank.
