We're like Laurel and Hardy when it comes to a puncture.
Spend an afternoon taking your tyre on and off, punctures are a ball ache, no need to make it last longer than need be!
Also as Bothwell says, put as much weight on the bike as you can... A loaded back pack is likely to be very uncomfy after 50 miles...
