Wow - this has been an incredibly helpful thread for me too. My first 2 triathlons I've finished at the front of my group after the bike but then get passed by like 20 people on a 5k run - it's miserable. My hamstrings generally don't get as sore as other parts of my leg (especially my calves) on a run so I might try working on the kick. I'm starting track workouts this week but it sounds like getting better will be a longer-term thing - maybe a year or two before I get down to those 7 and 8 minute miles from my current pace of 10-minute miles (I know - really, really slow). Thanks again!
