The Southwest Face route (which has also been called the Weenie Route or the Beanie Route) is as follows:
This route is a car to car via the scramble up the southwest face of Greyrock. Follow the Greyrock trail for about two miles up to the junction below the rock. Make your way up to the southwest face to the gully in the picture. Begin the scramble here, as the gully dead ends search up and right on for some easy climbing to exit the gully. From here you will round out to the south face of the rock and follow some intuitive movements up towards an obvious summit. Bomb the descent off to the east of the summit back down to the trail junction and finally to the parking lot. All moves are 4th or low 5th class with limited exposure, anything harder and you are off route.
There are two scrambling routes up the Southwest face of Greyrock, the one which has previously been labeled as the Weenie route is forgettable and has an exposed move. This route has been made into a Strava segment and named the Weenie Loop. It has a hard 2,000 climb in the first two-ish miles, a fun and technical scramble, and an extremely technical steep descent.

Here's another Strava segment on a slightly different route: https://www.strava.com/segments/7179207?filter=overall
Obviously, if you are going to claim the FKT you will need to beat the Strava times!
