4iiii Frontier – 161km (100 Miles)
The 4iiii Frontier Route is the ultimate 100-mile gravel challenge at THE RANGE.
At 161 km, the Frontier builds on the Classic Range route and adds an unforgettable out-and-back adventure down West Sharples Road into the spectacular Oldman River Valley. Riders will leave the rolling ranchlands west of the Porcupine Hills and descend into one of southern Alberta's most dramatic landscapes before turning around and climbing back toward the heart of the course.
This premier route delivers everything that makes THE RANGE legendary: endless gravel roads, expansive mountain views, rugged ranch country, and a true sense of adventure. The descent into the Oldman River Valley provides a completely new perspective on the region, combining big scenery with a rewarding challenge that will test both fitness and pacing.
For riders looking to conquer a full gravel century, the 4iiii Frontier offers the perfect balance of distance, challenge, and breathtaking Alberta landscapes.

4iiii Frontier Map:
Oh, I love these wild flowers in this dear land of ours,
The curlew I love to hear cry,
And I love the white rocks and the antelope flocks,
That graze on the mountain slopes high.
