This year I was on about a 3:05 pace at that point and ran the entire Ws section without any traffic other than a few yahoos who felt they had to sprint to this section then walk. In years past, I have been on a 3:15-3:30 pace through the Ws and have only been forced to walk for maybe 50-100 feet due to traffic. Honestly this is only due to people who have no business running up to the Ws doing so and then walking and clogging up the trail. Either way, this only slows the pace by minimal time losses and actually forces a relaxed effort which helps out further up the trail. It may be annoying, but 30 sec to 1 min lost in the Ws will never blow a race, especially if you are not the top 1-5 front runners, in which case you would not have traffic issues anyway.
