Looked like Bill hit a dead stop on one of the small bumps before the long climb started, so beware!
The ending wasn't as steep as I thought, and quite short (5-7% gradient). The deadstop section is at a 18% bump in the beginning of the last third. If you add me and @BILL S you will find we respond differently on that section with me experiencing the stop a little later. Thanks to @BILL S for providing me with a perfect pace, but probably it is possible to shave at least a minute or more from the time, given the December league results in the 15kms stage.
