jonny seriously, buy a rock hard saddle. in the long run it will help. bibshorts are good if you are doing a long run but for 7 miles i would think that is excessive.

The problem with a soft saddle is that it will allow some of the padding to creep into recessive areas (and exert pressure) that evolution deliberately kept out of harms way - a harder saddle will protect the crown jewels much more than seems commonsensical.
Although in the short term (a few days, perhaps a couple of weeks) a stiff saddle might feel a bit hard but it will become your best friend after a while (I recently went out for a drink with mine and ended up sleeping with it in a £12 hotel - it felt so dirty).
I did this years London to Brighton on a Selle Italia SLR and cut down jeans (commando style).
The rest of my friends did the whole gel saddle + padded shorts + gel seat cover (I rode around on one it was like sitting on jelly) - my arse won ! - I had zero discomfort - pretty much everyone else complained about their sore arses.
