Cynthia - Well said - I agree
The best way to get a Skyline ascent record is to have a race where everyone is running under the same conditions under the same temperature with water stations and monitors where runners are tempted to take short cuts.
There could also be a race where short cuts are allowed, but this would have to be kept secret. I do not recommend this alternative however.
