It is a touch shorter but not that much really....maybe 1 second vs my 15!! We measured it a while back when we setup the track for the 10 miler and the 40k's and it surprised us at how there was hardly any difference in doing a "wider" ride around the track for the 40k's (probably a 20 ft wider radius). It was a tad shorter finishing on pit road than the main track but not as much as you might think.

But we still DQ riders who complete their last lap on the main track vs Pit Road because they didn't follow the rules!!!
