Race planning

Plan Extremo Sul Ultramarathon

Use the listed edition as your starting point. Each tool keeps imported race facts separate from the targets and assumptions you choose.

Recorded facts reviewed Aug 19, 2026. Check the organizer’s latest rules. Calendar downloads use all-day dates and do not set a starting alarm.

Pace & duration

Start with the recorded course distance. The recorded duration or cutoff is filled in; adjust it to your goal.

Choose a checklist suited to your expected duration. Add the organizer’s mandatory gear.

Bring across the race name and local start time. Add confirmed access points, distances and your own arrival estimates.
