I'm pretty new to cycling. Past experience is all running. Just bought my first real road bike, past cycling has been about a 3 month period of mountain biking while training for an Xterra.

Got about three real rides in, two were about 10 miles the other was 15. Pace has been right around 3.5 min/mi. Just trying to build up for an Olympic distance triathlon the end of June. Road cycling seems to be more about pace than the mountain biking, which was more technical. What should be the plan for pacing? I plan to ride about three times a week with a long ride on the weekend just based on my running knowledge. Should I be more concerned with cadence, speed, heart rate???
