Heart Attack is an awesome downhill trail. Every corner has a berm so you can rail through them. It is just steep enough to be fast and fun. And there are minimal rocks except for a few which make good jumps.

A good option for a climby medium length ride to get some of the more popular big views Susanville Ranch...

Great after work route to get some good descending in without too much climbing when you're short for time.

This is a good two way trail to access the trail network. Starts out with a mellow ascent to get you warmed up, then increases in steepness with some punchy sections that earn it the name "heart attack". Berms are for the most part the only downhill feature, could benefit from some optional side hits and drops to make the descent back to the parking areas more engaging.

Ride this up and down. It’s a heart attack going up. Some sections quite steep. Ended up walking little parts. Overall doable. Down is super fun! Flowy, terrific build with nice berms and some fun rocky sections.

Has a great flow both up and down. Very well maintained with near-perfect berms.
We hope you've been enjoying Trailforks!
