This route starts and ends at the Rose Bowl in Pasadena.  Turn around point is Cloudburst Summit via Angeles Crest Highway / Highway 2.

Good loopf for hill training.

The hill on Rancho San Rafael is one of the steepest around Pasadena.

A loop takes about 45min.

Named "Vass" Loop after Steve Vass, the inventor.

Very good for a weekday workout.

It has a bit of everything: moderate and steep hills, flats.

Good for speed training, time trial, triathlon simulations.

Good if you only have one hour to work out.

Also good alternative to the Rose Bowl.
