Training for my second LA Marathon under a 3/2 program (3 days running, 2 days cross training) and looking to buy a road bike that I can ride 2 days a week for 45-60 minutes. Would like something I can train with and use for shorter triathlons if possible. I'm 5' 8", 155lbs and have been measure (today) for alignment to a 52cm frame.

Budget is $1000-1500. Thanks in advance for any help...
