This mountain provides the backdrop for every picture taken of the Las Vegas Strip. It is easy to get to for all tourists and locals, and seems like a natural FKT for Vegas. The view from the top (Lake Mead to the East and Vegas to the West) is outstanding. There is a Strava segments for the ascent, the descent, and round trip.
I'm tentatively planning to go up Frenchman Mountain this Saturday morning (Nov 10), and if I do I'll bring my InReach and track the time to set a baseline FKT on this route. It is indeed a great Las Vegas viewpoint!
I completed an up-and-back of Frenchman Mountain yesterday, will submit the details. There are 2 possible "highest points", so having not figured this out in advance I went to both of them. Looks like the northern point is higher (both the peak elevation and the max attainable height on the trail before running into a gate). It's called "Sunrise" on the topo map, and it's also the more obvious point from a distance. I'll report my uphill split to that point. Fun climb, rocky downhill, beautiful views.
Update: My times didn't beat the Strava course records, I'll pay more attention to that for future FKT attempts.
