Hi all!

I'm not new to bike riding (last time I seriously rode was in elemenatry school), but I am new to commuting long distances. I work approximately 20km highway driving, and it may be a little longer by using local trails. Just wanted to ask some people here with experience if this is too far for a begginer. I am pretty athletic. 5' 7" 160lbs. But I'm taking up the sport too lose a little weight. I just purchased a Specialized Sirrus Pro Disc. Thanks!
