A summit bid (or summit push) is the attempt to reach the top of a mountain, typically the final, committing stage of an expedition launched from a high camp. Summit bids are timed for a weather window and good conditions, and require turnaround discipline — committing to descend if the climb runs late or conditions deteriorate.
Timing it
Teams wait at high camp for a weather window, then launch with an alpine start.
Turnaround discipline
A set turnaround time guards against summit fever — especially in the death zone, where delay is deadly.
Frequently asked questions
What is a summit bid?
A summit bid is the committing attempt to reach a peak's summit, usually the final push of an expedition launched from a high camp during a window of good weather. It's the culmination of all the acclimatization and camp-building that came before.
What is a summit window?
A summit window is a period of favorable weather — calm winds and clear conditions — long enough to climb to the top and descend safely. On big peaks these windows can be rare and brief, so teams position themselves at high camp ready to launch when one opens.
What is a turnaround time?
A turnaround time is a pre-agreed time by which you must turn back from a summit bid even if you haven't reached the top, to ensure a safe descent in daylight and before conditions worsen. Honoring it is a hallmark of good judgment; ignoring it causes many accidents.
