Triathlon question
2 miles in 25 minutes seems to be pretty respectable. That means you are getting close to 12 minute miles or 5 mph which is great for just starting out. The more you do it, the better it will get for you. You have to start somewhere. Do whaterver it is that get you out there and active. If you have to walk, then walk. That is much better than not participating at all. Good luck with the Tri and let us know how it went for you. Scott
The first time you do something - It's going to be a personal record!
If you walk the race director comes by and hits you with a big stick! Just kidding. Of COURSE you can walk and you'd be surprised at just how many people do walk. There's no shame in it.
Guess what they call the guy or gal that walks across the finish line? A triathlete. It's not about winning. It's about beating the course.
