How to promote a book on biking cross-country?

If this post is inappropriate, I apologize, and please delete.

I've written a travel memoir on biking cross-country. Yes, I know I'm not the only one to have done such a trek — you may have, too :-). But I do need to promote the book, which will come out in a couple months, and I'd appreciate any advice.

Thoughts as to a well-known cyclist or adventurous traveler who might want to write a blurb (like, 2-3 sentences)? I heard Al Roker is one, but I can't figure out who his agent is. I wrote to Leon Legothetis (not a cyclist, but still...) yet haven't heard back. Anyone accessible come to mind?

Or thoughts on podcasts/blogs who may be open to having me?

The manuscript focuses on the human stories of people I met along the way, along with beauty and kindness.
