How to read map?

[Over50Newbie]

Hi everyone,

As you can see by my screen name, I am brand new. I am participating in my very first mini triathlon, and just received a course map. Only, I'm not sure how to read it.

Here is the link:

How steep are those hills in the biking section? They sure look big to me! I am not that strong of a rider, but I am generally in good shape. I will be riding on a Trek Navigator 300. Will I have to walk my bike up any hill? If not, what gear do you think I will have to use?

I'm starting to get nervous!

Any help at all will be appreciated.

Thank you,
