What is the best time of year to jog this loop?

What is the terrain like on the loop?
The loop offers diverse terrain. You'll start on a gentle dirt road through Las Llajas Canyon Trail, transition to a broad, often rutted and rocky fire road on the Rocky Peak Trail, and then encounter a technical, rocky singletrack on the Chumash Trail. The very end includes a short section on a paved residential road.
What kind of wildlife might I see along the way?

From higher points like "Fossil Point" near the top of the Chumash Trail, you'll get spectacular panoramic views of Oat Mountain, the San Fernando Valley, San Gabriel Mountains, Santa Monica Mountains, Simi Valley, Boney Mountain, Channel Islands, and Ventura Mountains. You can also find fossil shells at "Fossil Point."
How long does it typically take to jog this loop?
For an average jogger, the entire 26.5 km (16.5 miles) loop typically takes around 3 hours and 17 minutes to complete, depending on your pace and how often you stop to enjoy the views.
Is the Rocky Peak, Las Llajas, and Chumash Loop suitable for beginner joggers?
This loop is rated as difficult due to its significant elevation gain and technical sections, particularly the rocky singletrack of the Chumash Trail. It's more suitable for experienced joggers with good endurance and trail running skills.
What should I be aware of regarding other trail users?
The Rocky Peak Trail section is popular with mountain bikers, so joggers should remain alert and be prepared to share the trail. Always be courteous and communicate when passing.
What is the best direction to jog the loop?

This allows you to get the major climb out of the way early and enjoy the challenging downhill. However, running down the Chumash Trail requires good skill due to its rocky nature.
