The Ridgetop Run

A trail boss at Ridgetop wants the summit run timed before the snow closes the pass.

Requirements

Meet the trail boss at Ridgetop Bank
The trail boss has a stopwatch and a creased map. 'Snow's a week out. I need the summit run timed in fair weather before it closes. You're the legs I have on hand.'
Run the lower trail at pace
The lower trail breaks even. You hit the first marker three minutes inside his bracket. He marks it on the map without comment.
Cross the hollows without stopping
The hollows are slick where the sun didn't reach. You take the long line across the upper edge and lose only ninety seconds. The boss's runner up here just nods.
Touch the summit cairn
The cairn is half-buried in old ice. You touch the top stone and the boss's second runner calls the time from a hundred yards back. You're under his target by a full minute.
Descend through the venture route
The venture route is the dangerous descent. You take it at three-quarters pace and still close out the run with breath to spare. The marker post at the bottom is fresh-painted for the timing run.
Report the time to the trail boss
He copies the time twice and signs both. 'Under target on a cold week. The pass closes in five days. I'll print this as the standing record until the spring run.'
