Another Chicago Tri Noob

Hello. My name is Scott and I live in the south suburbs of Chicago . . . but why am I here ? My company chose me to take part in a team triathlon this coming August 25th. I was chosen to do the swimming portion of it, and I am excited to try, but extremely nervous to try. I have never done anything like this and have been trying to read up how to prepare for the last few days, as well as actually getting in the pool.

The good news is I am in good condition for the most part. I am 30 years old now, 5' 7", 165lbs. I play racquetball, and 16" softball often, and for the last 5 months have been working out every day and eating very healthy. So the steps leading up to me being selected are all positive.

After a couple days in the pool however, I have realized just how extremely tough this is going to be. I've basically just been trying to do 50m laps in the 25m lap pool with a 45 - 60 second break in between. I get fatigued rather quick, but I think it is due to me over-doing it. I think I just need to relax, and remember it's a marathon, not a sprint ! I am able to around 20 laps like this for right now, and each lap takes about 50-55 seconds.

I am very motivated about this challenge, and am taking it very serious. I just hope there are enough days before Aug 25th for me to get into swimming 1500m shape !

Obviously any tips would be much appreciated.

Thanks all !!
