Best Event suffer

Hello

I came to Triathlon from road biking.  So prior to getting bite by the tri-bug I road my bike 4 plus days a week to include weekend rides of 40-60 on Saturday & Sunday.

So in June 09 I dicided to get out of my comfort zone and do something different. Triathlon seemed like the ticket to really work my now 50 year old body.

Today after 6 or 7 weeks of tri training I wanted to go on a longer bike ride like I use to do every weekend.  I took my swim test, did a little T-1 practice and jumped on the bike.  After timing my 10 mile Sprint distance I continued with the rest of my ride.  I found that my legs were very sluggish the last ten miles of my 33 mile ride.

So have others had this same situation where your strong event prior to starting triathlon training suffers trying to get the second two parts up to snuff?

So for me my bike riding seems to have suffered as I continue to work on my swimming and running. I will say that I am in better shape and my I have more muscles showing in my chest, arms & legs. 

I am fine with the change but was wondering if others have this same situation.
