Any question answered...

Hippy - where you leaving from?

Southall to Twyford about an hour, plus rush hour madness.

The A4 is pretty solid until M25. M4 also solid, but clears a lot earlier, then gets manky again about the M25.

If I HAD to get there at 6, I'd leave Southall at 4, and probably arrive at 5.30.

Obviously you can't get train?

Ealing to Newbury, two people, two bikes. Maybe A40/M40 is better?
