This one has two challenging climbs for about 1000' in a 10 mile loop, so you can do as many laps as you want. Start the route from Salvia Canyon to Linda Vista north.

This is a 40+ mile ride with over 3000' of climbing going up the famous Big Tujunga and down the famous Angeles Crest, or you can reverse it. Jump on from the Rose Bowl by heading north up Salvia Canyon, right on Linda Vista, then right over the freeway to a left on Oak Grove.

35 miles with about 2000' of climbing including La Tuna Canyon. The pavement down Wentworth isn't the greatest, but it's still a nice ride. You can also catch this ride by taking Salvia to Linda Vista north and across the freeway to a left on Oak Grove.

Hope that helps, and I'm sure there will be plenty more options once other chime in. Enjoy your riding!
