We rode loaded ADV bikes from Terrace to Telkwa, so heading down from 10.4 km on this map. At 2.6 km there is a water crossing for about 130 ft, and it was maybe 2/3rds up my mx boots. This obstacle is easy compared to the rest... if it gives you trouble, turn back. At km 8 there has been a massive rock slide, maybe 1000 ft across. Heading from Terrace to Telkwa on a loaded ADV it's unrideable, you will have to pull your bikes up the hill one arm length at a time. It would be downhill from Telkwa to Terrace, so more doable. From 10.4 to 2.6 km on this map took us 5.25 hours. From the first obstacle on the prior road segment to the last is 10.3 km which took us 10.7 hours to get through.
