As for Baxter Creek, if you're the kind of person who thinks they can hike 22 miles in one day, then you should be the kind of person that can hike Baxter Creek. But like TNhiker says... it's quite a haul. It's about a 4,000' climb in about 6 miles. That's an average of a 12% to 13% grade THE WHOLE WAY. I would suggest that you allow yourself 6 hours to tackle that hill.
But a bigger question would be WHY? Why this particular loop. I don't recall there being much to make hiking Mount Sterling Ridge and Balsam mountain all that interesting. If you want a loop with some big miles and more interesting scenery, I would suggest parking at the Big Creek Ranger Station near the Chestnut Branch trail. Then hike Chestnut Branch to the AT to Mount Cammerer, check out the lookout tower, then continue on the AT to Cosby Knob shelter. Then the 2nd day, hike down Camel Gap and up Gunter Fork and then Mount Sterling Ridge to #38. Return to your car via Baxter Creek and a little less than a 3/4 mile road walk back to Chestnut Branch. I don't recall much of anything memorable to hiking Camel Gap Trail, but the hike down Camel Gap with worth some of what there is to see on Gunter Fork.
