It was 1 hour of sprints, then 3 hours of lbp.
Went from Oxted to the lanes near me for the sprints. Then took the back route to Redhill (up Tilburstow Hill - going a bit faster up there these days thank God) then along the A25 for a bit, into the back of Redhill via Philanthropic Road, into south Reigate near the Angel, and then on the back roads towards Horly. Followed the reverse CR till our normal turnoff then Horne, Blindley Heath, Hurst Green.
Don't know how many miles it was, I've stopped looking at that and my ave speed these days. I was very pleased to finish though, I can tell you.
Don't know how you can do all that training in the dark. I go out from work at lunchtime. I work in Reigate so I can be at Flanchford Road in 5 mins. Nice
