If you love the grit of the Green Monster, then sign up for Tyoga Running Club's RISE & RUN ! We’re stripping trail running back to its purest (and earliest) form.
Rise & Run isn't your typical pampered race. It’s raw, it’s fast, and it’s built for the community. Here is why you need to be there:
The "WTF" Start Time:
We kick off at 3:59 AM. Experience the woods in that magical, quiet pre-dawn window.
Old School Support:
Forget the buffets. We have one aid station. Bring what you need, find your flow, and keep moving.
Insane Value:
We’re keeping it affordable so you can keep running.
$25 for the 25k
$50 for the 50k
No fluff, just miles and a massive sense of accomplishment before most people have even finished their first cup of coffee.
DID I MENTION IT TAKES PLACE IN THE PA GRAND CANYON? RISE & RUN IS TRULY UNIQUE!

Our Green Monster crew has come through with set up. We are ready to see all of our Monster family bright and early rain or shine!

Extra big thank you for all of our volunteers over the past few days. We would not be able to host this event without you!

Huge thanks to all of the participants! None of this would be possible without our crazy monster running family! If we had no runners we would not be here!

Aid station teams we appreciate you so much! Our runners would be lost without you.
