My commute will be from Ealing in West London to Marylebone in Central London which will take me through Acton , Sheperds Bush , Notting Hill and Bayswater . Any tricky points along the way ?
Your ride in will be a breeze as the wind runs to the east in the mornings, coming home will obviously carry the penalty.
If I were you I'd avoid the A40 Westway and drop down onto the A402, through Holland park (still pretty busy but more prone to having a good bus lane to ride in).
Failing that drop further south still and ride along Kensington High Street and through Hyde park (glorious) to Bayswater, this is the first few miles of my ride home (Shepherds Bush to Kent) and I really enjoy it. Breaking at the park to run past the Albert memorial is lush and the sun on the serpentine in the mornings will be worth the additional mile or so.
Perhaps, if you allow time grab a latte at the tennis club in the park, you can call your order through the door and wait outside under the brollies (so never leaving the bike)...then sit back and sip whilst you spot celebs running circuits round the lake, perfect
For hints on riding in traffic follow AKB's link, its a great guide (although I'm a little biased)
