Last Minute Tip for 1st Ave: Remember your 4's!

There is an easy way to remember where it goes up and where it goes down:

It is a steady downhill to 74th.

Then, it begins to climb until 84th.

Finally, you run downhill again until 94th.

Above 94th, it is flat all the way to the Willis.

If you're thinking about this instead of the roaring crowds, you may be taking things a bit too seriously - but it doesn't hurt to know! Have fun out there, and good luck to all!!!
