Susan is an amazing instructor, she knows how to keep you going and pushes you to the next level. Her music is a great mix of the latest and greatest and then some throw backs. She takes requests if you want to do more of less of a climb or in the saddle. She listen and hears what her clients are asking for and changes up the class, which is important and keeps you coming back for more because you never know what she has in store for that day. She walks around class to sort of give you that extra push just as you are getting ready to bring your speed down.
