The link below is to a little place that is northwest of me near Woodville, MS. I have made mention of this area before, but it may have been missed. The link to the pictures don't show the single track trails that go around. But I have good GPS data that gets you a little over 2000 feet of climbing (2035 feet to be more exact) in a 4ish mile loop. It doesn't get any better than that here, and you can get some hill training in that is probably good for any race where altitude is not an issue.
Cool. Thanks for the info!

They have a couple of little cabins just off the property you can rent, too. I'll be back up there right after Christmas and get the information. It would be good if you wanted to get some b2b climbing days in or something.
