Looking for a quick way to get to the summit of Rockfellow, don't want to shove your body inside a crack of any size? Fast Track will have skipping to the front of the line like a Disneyland fast pass. Only caveat is you have be able to slab climb. All said and done this is an enjoyable route with great views and minimal runouts. 

P1 Gain the slab by stepping across to a foothold from the boulder, a bolt protects the stout step across. Climb passed another bolt and gain the grainy crack to one more bolt. From here you'll have to do a few moves to get inside of the large chimney system, these moves seem weird at first but once you figure out the beta it is quite reasonable. Minimal groveling will get up to the two bolt anchor at the base of the ear flake that starts pitch 2.  For reference there is a loose tree/bush thing where you get into the chimney. The bolted anchor is about 6 feet above the foliage on climbers right side of the chimney. This anchor can be hard to spot.

P2 Climb the ear flake, set some high pro in what seems to be rotten rock, the piece I got was good. Slab traverse passing three bolts (mild runs between the bolts) until you reach a very welcome crack, this is where Fast Track and Cliffhanger intersect, a few steep moves and a couple more bolts get you established on the beautiful chickenhead arete that takes you to the base of the amazing 5.7 crack to the sub summit of Rockfellow. 

P3 5.7 glory crack or a bolted 5.10 pitch to the left of the crack, both are easy to see.

The Tanya Bok guide provides nice photo beta.

This climb starts off of a giant boulder tucked back in the E facing amphitheatre that houses Maniacal Bagel and the convenient east face rappels off of Rockfellow. The climb is just downhill from where the rappels deposit you. Look for a lone bolt on a slab that you access by scrambling up the large boulder. 

A single rack from .3-3 will provide ample protection. 6 long slings and 6 draws
