The Redwood Anvil is a 10 mile loop composed of 6 distinct segments, each offering their own challenges for the runner:

Segment 1 – Wire Pulling (miles 0 – 1.0)

Like a blacksmith pulling wire, this first segment forces the field from a wide, flat, paved path into a narrow single-track dirt trail. Contenders will want to get out fast for room to run free. Please practice patience and good sportsmanship with your fellow runners.

1. Start onto paved Stream Trail.

2. Over bridge and hard left onto connector to Bridle Trail.

3. Quick, hard right onto Bridle Trail.

4. Continue on Bridle to Chown Trail. Single-track trail running and rollers, rollers, rollers.

Segment 2 – Tongs (miles 1.0 – 2.6)

Tongs is the segment that picks you up out of the canyon and drops you onto the ridge. If you’re a strong climber this is where you can flex and make a big move. But be careful not to burn through too much of your glycogen stores, there’s more climbing and too many good running miles ahead. Tongs can feel like a mini climb to Devil’s Thumb for those who know the Western States Trail.

5. Left and UP on Chown Trail.

6. Continue on Chown to French Trail.

7. Soft left onto French Trail.

8. Continue on French to Orchard Trail.

9. Right on Orchard up to West Ridge Trail.


Section 2 - Tongs



Segment 3 – The Press (miles 2.6 – 4.9)

Welcome to West Ridge Trail and The Press. This is the third segment and second longest. Climbers who conserved on Tongs will be rewarded with a steady climb or PRESS up to the highest point on the course near Redwood Peak. If it’s a clear day you can catch views of the Bay on your left and Mount Diablo on your right. At the top you will pass by Redwood Bowl and Chabot Space & Science Center on your left before descending into the aid station at Moon Gate.

10. Right onto West Ridge Trail.

11. Continue on West Ridge to Moon Gate Aid Station.


Segment 3 - Press



Segment 4 – The Forge (miles 4.9 – 6.5)

A forge is a furnace where a workpiece is heated before transfer to the anvil for hammering. At the midpoint on the course, The Forge is where your legs will feel heated and malleable, and what you did up to this segment will determine what you can do in it. After leaving (or blowing past) Moon Gate Aid Station, watch for the quick right hairpin turn onto Tres Sendas Trail to go back down into the canyon. Down, down, down… Careful with the rocks and roots, these are the most technical trails on the course. And remember to stay left to make the transfer onto French Trail and up, up, up out of the canyon and back onto West Ridge into Skyline Gate.

12. Continue on West Ridge Trail for about 100 yards to Tres Sendas Trail.

13. Right onto Tres Sendas Trail.

14. Continue on Tres Sendas to French Trail.

15. Left onto French and up to West Ridge Trail.

16. Right on West Ridge Trail.

17. Continue on West Ridge to Skyline Gate.


Section 4 - Forge



Segment 5 – The Hammer (miles 6.5 – 9.5)

Finally… The Hammer. This is the top of the “anvil” and longest segment on the course with good visibility of the field. Hammer it! Three miles of solid pain for the contenders. If you’re hurting, be sporting and try not to show it, and if you’re strong, pull away or reel them all in. Almost there… Oh yeah, check out the views on East Ridge Trail!

18. Skyline Gate to East Ridge Trail.

19. Continue on East Ridge to Canyon Trail.


Section 5 - Hammer



Segment 6 – The Finisher (miles 9.5 – 10.0)

The Finisher is the final segment and it’s all downhill to the Finish Line. Gravity is your friend and pacer here. Fast leg turnover works well on this segment and don’t look back — we don’t want you to fall. Roll baby, roll!

20. Right onto Canyon Trail and down into the Finish Line (or Start/Finish Aid Station for 20 milers).
