MAXXIS ESC Cannondale Enduro Series at Diamond Hill, RI
Presented by Shock Lab
April 25-26, 2026

April 25-26, 2026 MAXXIS ESC Cannondale Enduro Series
A racer favorite, Diamond Hill holds the record for the most consistent sell-outs in the Maxxis ESC Cannondale Enduro Series. The coastal climate ensures an early opening, though racers should prepare for temperamental New England weather with appropriate mud and rain gear.

The terrain at Diamond Hill is demanding, featuring steep rock slabs and technical rooty sections. While these technical sections are a highlight, the flatter portions will reward riders who maintained their off-season training. This is a fully human-powered event, requiring racers to pedal all transfer stages. Some stages will be across the street on RI State land!!

CAMPING
Directions to access the camping areas:
Cars/Pickups/Vans – Must use the Fisher Rd Entrance:
19 Fisher Rd, Cumberland, RI 02864 is a private residence, but this is the best address to use for GPS navigation to the Diamond Hill Park Trail gate. The gate is just past the residence on the right.
RVs and Trailers – Must use the Diamond Hill Rd Entrance:
We have a very limited number of spaces available for RVs and small camping trailers. These spots will be in the main gravel lot at 4097 Diamond Hill Rd, Cumberland, RI 02864.
You can’t race without a good night’s sleep. We got you covered with on-site camping right at the trailhead.
Overview:
Celebrating 10 years since the first Enduro held at Diamond Hill, the RI Chapter of the New England Mountain Bike Association (RINEMBA) has been working hard to bring back an old MAXXIS ESC favorite. Returning racers already know that this Rhody-sized trail system delivers big mountain gnar. Despite a record-setting blizzard in February, trails are looking prime for the official launch of the 2026 MAXXIS ESC series.
The Town of Cumberland has graciously made an exception to allow camping! Sites will be a combination of open grass fields and a gravel lot.
The only thing RINEMBA likes seeing inflated is tires — so overnight parking for the weekend is the same fee as it was in 2022 at $30/vehicle. The RI Chapter is part of the regional NEMBA 501(c)3, and all proceeds will be allocated directly to trail building in RI!!
Space is limited, so your cooperation with our volunteers is greatly appreciated.
- ALL campers must register in advance.
- Check in is between noon Friday and 6pm Saturday
- Only 1 vehicle per site
- Dry camping only, no hookups. Portable toilets provided
- Carry in, carry out all trash. Plan accordingly.
- Please plan to be packed up and outside of the camping area by 5PM Sunday April 26th.
Behavior & Conduct:
Follow volunteer instructions at check-in between noon Friday and 6pm Saturday evening.
Quiet hours 10 PM–6 AM. This is a town park, with homes nearby. We’d love to be welcomed back next year.
