London is a point to point downhill course with a big tailwind on some years. Maybe they should increase the downhill gradients or something and have big fans blowing behind the runners?
The big tower blocks at Canary Wharf tend to have wind tunnel effects - can be quite strong gusts in that section of the course, both for and against the runners. Most years, the last 6 miles are directly into the wind. It's never going to be the fastest course.
World Athletics (IAAF) specifications considers courses not to be point to point and downhill if they meet the following criteria (same as for World Records):
Separation (straight line distance from start to finish) = less the 50% of the total distance.
Drop (elevation change from start to finish) = less then 1 meter/kilometer
Based on the above, London is not considered downhill or point to point.
In addition, the NY Marathon also fits into that category - the separation is less then 50% and the drop is within the allowable.

So you missed the bit when I wrote "Do a 90r. Then do another 90r. Which way are you facing?"
90r (i.e. 90 degree turn to your right).
90r then 90l would be straight on.
