Glad thing's worked out ok. So was the ride through the tunnel ok. Leaving Heathrow I found that to be the best bit....the roundabout at the other end was a bit scary. Actually my time riding in London a couple of years ago was a pleasant surprise as there were lots of bike paths and the drivers seemed to be pretty good about giving bikes space. It was a lot better than in my college years, back in the 1980s, when I rode a bike in London.
