Snicks, I'll certainly run with you if you like. Jon, isn't your 10k time in the 41 - 42 region? In that case, you should certainly be able to go sub 1:40.
Based on my 10k time of 43:26 last week (sorry, I had to mention that again!), Bob Glover's tables predict 1:36 or so. But I haven't run since Sunday (tube strikes Tues and Weds meant I got home late and tired) and I've just come down with a stinking cold, so we'll see.
But a group of us running at constant 7:30 pace sounds good to me. Count me in.
