Managed to get the bike in to ExCeL today. That place is huge. I have some pics of the main hall that they're using for transition, but I don't think I could do it justice. The weather was atrocious... lots of wind and rain (I cycled in from Plaistow so still had to suffer a bit). Fortunately the forecast for tomorrow is looking much better. I think I've got everything planned out... just hoping for no awful last-minute surprises! Wish me luck!
