Hi I'm Santi, and I'm a content marketing manager in the tech industry by day and grad student and writing instructor by night. I’ve always loved biking, ever since I got my first bike on my fourth birthday. As a kid, my siblings and I would go on biking “adventures” around the neighborhood, pedaling our way to nearby schools and lakes. Naturally, those adventures have only increased over the years! In addition to biking, I also love telling stories and traveling around the US. I write about our biking adventures and about fat bikes for women and kids.
