Well I think I'm hooked.

Regarding the transition from bike to run, some people are more affected by it then others.  I personally have no troubles and some folks take a bit to warm up.  I suspect as your conditioning improves though, both on the bike and on the run the easier it will get for you.  It also depends on how hard you go out on the bike as to how you might feel on the run.

Good for you for making a life change like that.  Keep it up

Congratulations on your accomplishment first off!

Regarding the bike to run transition, I have found that as your bike fitness increases it will be easier to run off the bike. Maybe a couple times a week try to do a short run of 1/2 mile or so after you bike. Also if you push a big gear on the bike it will also affect how your legs are off the bike. I found it helps a bit to go to a lesser gear and a bit higher cadence near the end of the bike to flush the legs and help prepare them to run. Just watch your pace at first running and dont go out too hard, I find that after the bike I am used to my legs moving fast and it easy to over do it on the first part of the run. Hope this helps!

Awesome, keep up the good progress

Congrats on your addiction.  It'll only grow when you do your first triathlon

For the bike/run transition - yes, its a very real phenomenon that virtually everyone experiences.  Here's some more information on the science behind why it's difficult:

For what it's worth, a friend of mine noticed that when he switched to a tri-specific bike, his transition was much easier.  I'm not sure, but I'd guess that is a pretty common scenario with a tri-bike - with its different angles, it may very well do a better job of getting the posterior chain and the glutes involved to make the transition easier.

Two months of training equals a habit for which there is no cure!!! Welcome to the addiction and congrats on the lifestyle change. Who knows maybe your dedication to your health may get one of your fellow bar buddies to make a change of their own.

The bike to run transition will get better with time and training. Seeing as your just getting started training I wouldn't incorporate too many bricks just yet. Crawl before you brick!!! Give yourself some time to get your aerobic fitness up a bit and then drop a brick or two into your training here and there. Don't do too much too fast and get frustrated.

That's awesome. I was much like you--always set out to "get in shape" but never really stuck with anything. Getting in shape was such a vague goal.

Triathlon is a whole different animal. When you know you have a race coming up, that changes things. I know if I don't train, I'm in for a sufferfest or a DNF. That motivates me.

So if you haven't registered for a race or two, I recommend doing so. Good job!
