Every mountain biker knows the frustration. You check the weather, load up the truck, drive 45 minutes to the trailhead, and find out the trails closed two hours ago. Nobody texted you. The Facebook post got buried. The website still says “Open” from yesterday.
fullsndr fixes this.
How It Works
fullsndr monitors trail websites every five minutes. When a trail status changes from Open to Closed (or back), every subscriber gets an instant SMS and email alert. No app to install. No social media to check. Just a text message when it matters.
Why It Exists
Trail closures protect the trails themselves. Riding on wet, saturated surfaces creates ruts, channels water, and accelerates erosion. A single wet ride on a jump line can cause $20,000+ in damage. Trail organizations close trails to protect the investment that volunteers and land managers have spent years building.
The problem is communication. Most trail parks rely on their website, Facebook, or word of mouth. By the time you hear about a closure, you might already be in the parking lot.
fullsndr bridges that gap. We watch the trail status so you do not have to.
What is Coming Next
The free tier gives you real-time alerts. The Pro tier ($5/month, coming soon) will add predictive closures powered by weather data, soil moisture levels, and historical closure patterns. Instead of knowing that trails ARE closed, you will know when they are ABOUT to close and when they will reopen.
