I usually do the 21 mile Will Rogers – Temescal loop once or twice a year, and that’s just long enough to forget the difficulty of the strenuous climbs, and remember the outstanding downhill on the Backbone trail, great views of the city, and lush growth in Temescal Canyon.

If the day is warm the return from the coast can be particularly brutal. Today it was cloudy and cool for much of the run, and it wasn’t until the final mile on the Bent Arrow Trail that the sun broke through.
