Thanks to all who responded. I was hoping apache already had a 
configuration built in to do this. Instead of turning a variety of pages 
into dynamic pages in order to insert a sleep, I ended up writing an 
apache module and configured it with PerlInitHandler. This worked out 
well as I could configure it to just slow for my ip address without 
affecting anyone else. I could also easily apply it to all requests or a 
particular request via the <Location> tag.

In conf.d/perl.conf add this line:
PerlInitHandler MyDelay

Contents of MyDelay.pm are as follows:

package MyDelay;

# This package can be used in conjunction with a
# PerlInitHandler directive to slow down a connection
# based on an ip address

# Example: set in perl.conf
# To slow down a particular request
#<Location /delay_test.html>
#   PerlInitHandler MyDelay
#</Location>
#
# or outside of any Location, File, etc to slow down all requests
#  PerlInitHandler MyDelay

use strict;
use Apache2::RequestRec;
use Apache2::Const;             # for OK
use Apache2::Connection;		# for remote_ip

sub handler
{
   my $r = shift;
   my($c);
   my($ip_addr);

   $c = $r->connection;
   $ip_addr = $c->remote_ip;
   if ($ip_addr eq "my ip address")
   {
      print STDERR ("in MyDelay:handler\n");
      print STDERR ("ip_addr = $ip_addr\n");
      sleep (30);
   }

   return OK;
}

1;
