Dave and Amanda have teamed up with COROS to create a 10-week training plan designed specifically for the COROS Training Hub where Mammoth TUFF riders can follow the plan from their own account.

Whether you are taking on the TUFF, TUFFER, or TUFFEST route, this plan is structured to meet you where you're at.

⏱️ About the Plan:
-Tailored to Your Distance: Each workout includes a time range. We recommend following the shorter end for the TUFF course, and the longer end if you’re tackling TUFFER/EST.
-Listen to Your Body: Consistency matters, but rest is where we get stronger. If you’re too tired, it is always okay to rest and jump back in when you're ready.
-Based on Effort: Workouts are built off Threshold Heart Rate, with extra notes included for riders who train using power (FTP).

đź’» How to Access It:
The plan started this week, but you can incorporate it at any time! Rearrange the calendar as needed to make the start date unique to you.
-If you are a COROS user: Sync the plan directly into your personal COROS Training Hub account right now.
-If you are new to COROS: You can access the Training Hub and track this plan using any COROS watch. If you’ve been hoping to upgrade to their new DURA cycling computer, it's currently out of stock, but keep an eye out for the next restock!

đź“ť Why We Built This:
Our focus this year has been on offering as many resources as possible so you feel ready for a TUFF day. With Amanda having spent her racing career as a CTS athlete and Dave coaching with CTS, we know how much a structured plan helps. This COROS-specific plan is just another tool in your chest to help you prepare.

Attention riders!!
If you’ve ever ridden the Chipmunk trails in Bishop, PLEASE submit your feedback here. It’s critical we give input on what we love about Chipmunk to keep the consultants on the right path to good recommendations to preserve this place. Your voice matters and we love these trails.
