If we have time we will try for a 50 at the bottom of the hill.
The 50 cone got changed from “flat” to any slope. Please document if your 50 cone course is flat. Flat is: Flat : Having a slope of less than 1% elevation differential from start to finish
For the 50-cone course, this is 30″ (0.75m ) over the 257 ft (78.4m) course.
No Wind: Using a wind meter aligned with the direction of the course, an average wind speed of less than 16KPH (10MPH)
If the conditions of Flat and No-Wind do not exist (for 25-cone and 50-cone courses), the course shall be run in both directions, and the average of 2 runs (one from each direction) can be used for a World Record.
