Operational warnings

red · Operational constraint

The Peru Great Divide repeatedly exceeds 4,000 metres on remote, unsealed tracks with limited resupply.

An unacclimatised or poorly equipped rider can face altitude illness or an unrecoverable breakdown far from help.

Planning response: Use a dry-season window, acclimatise progressively and carry independent navigation, range and emergency communications.

Seasonal windows are planning triggers, not a substitute for current road, weather or land-access reports. Recheck the official sources below before departure.
