Ash- it varies of course according to the trail, but when there's an "obstacle" of any significance, everything slows/stops, spotters hop out and help everybody get over it.
With the CB radios, someone will often ask "when" next stop is.....so it's not really a problem.
Plus we always stop for lunch somewhere, so bring a bag lunch for your gang....and lots of water.
p.s. - The trail rules are girls on the right, guys on the left.
