Simplified trail layout
Here you’ll get a first overview of the planned trail layout.
The full route can be found in the section Masterplan Here we explain where and how we can make YOUR support visible.
The new trail park is being built east of the Ettlingen Albgaubad. It runs parallel to the federal highway from Ettlingen toward Spessart — bordered by the road on one side and the newly paved “Alte Steige” cycle path to Spessart on the other.
START PLATFORMS — SHORT BREAK, LONG IMPACT
Along the trails, there are three start platforms serving as clear meeting points. Ideal for catching your breath, grabbing a drink, and meeting up — right by the trail and easy to keep an eye on.
BLUE TRAIL, consists of three sections:
Five-Finger Grip (Deathgrip)
A flowy section with around a 7% gradient: rollers, gentle direction changes, and small table jumps keep the speed and fun high — often without needing to brake.
Mini Quarry Jump
A short, repeatable jump line with small tables — perfect for building your jumping skills safely.
Rollercoaster
A varied section with natural crests and ruts, complemented by berms and optional side hits — constantly in motion.
RED TRAIL, consists of three sections:
Sunken Lane
Three distinctive entries and exits into an old sunken lane: steep, technical, with optional side hits — with flowy sections in between.
Quarry Jumpline
A red-rated jumpline as its own loop: a series of medium-sized jumps, ending with a standout feature for some serious airtime.
Enduro Paradise
The most spectacular part: roots, crests, ruts, tight sections, and drops — plus two more challenging B-lines for the brave.
Yellow trails are connector trails.
They make it possible to ride individual sections multiple times — for example as a loop or in laps.

TRAIL COSTS
The construction of the Lehmgrube mountain bike trails will be carried out partly through the club’s own volunteer work and partly by professional trail builders using machinery. In total, the club will contribute around 1,400 hours of volunteer work on the trail. The costs for the professional trail builders amount to 92.500 € including VAT. The remaining costs add up from machine rental, transport of the machinery, signage, and unexpected costs.
Spending to date
We’ve taken responsibility and led the way:
- Contract with the City of Ettlingen signed — meaning we take operational responsibility for the planning, construction, and maintenance of the legal trails.Read more on BNN)
