Since the run is just under 2 miles most Chattanooga locals do laps on this stretch. Andy Dodson completed 10 runs in 1 day, capping it off with a run of Knuckle Head, in the Spring of 2004. The put-in is at the confluence of North and South Suck. If the water is high you may want to consider running South Suck as well. It joins in from the river right side at the confluence. Don't waste your time on North Suck, there's nothing up there worth lugging a boat to run.
Rocks are pretty jagged in Suck since there was a lot of blasting while constructing the road. Some drops have concrete debree, chain link fencing, and plenty of other trash dumped from people to busy to go to the dump.
Streambed formation is in flux; the rapids change more often than Madonna changes her image. You may want a local to take you down if you have not been down or if it's been a while. This run has serious consequences in otherwise innocent looking spots.
Rapids Include:
Optimus Prime- At one time the best on the river.
Road Construction (currently a rock in the entrace, most people going left of it; or use the river right line if there is enough water, the sieve seems to be filled in but exercise extream caution after floods)
