Bike Position

Are your aero bars too far forward? What is the angle of your saddle? Post pics and maybe we can help.

It's a fair guess that you're too stretched out. Since you said "bullhorns" I'm assuming this is a tri bike with aerobars. Is your seat far enough forward? Are your bars a bit too long? Is your seat tilted a bit too far down at the nose?

I have the same problem, BTW, and moving the seat all the way forward while fiddling with seat angle has cured most of it.

I think the real fix is to have a five or ten MM shorter stem to bring my arms back in a bit (I don't have adjustable armrests on the Vision basebar on my P3C).

... Sorry- I missed some crucial info...

It is a 54 cm Fuji Aloha.  I bought it used from craigslist after a month of researching bike fit on this and other forums.  It seems to be right, except for the sliding forward...

Im 5'8.  I don't honestly know what the geometry on the bike is.  I have the seat all the way forward and I have it as flat as I can from eyeballing it.  I have tried to tilt it up a little bit, but that hurts, ahem, you know what it hurts...

I have already moved the bars back a bit by putting a new stem on.  This makes the aerobars very comfortable on my arms and shoulders.  If I slide them back, my arm rests on them too close to my wrist and my wrists hurt for days after a long ride.

Im going for a ride tonight.  Maybe the pumpkinman course in South Berwick, ME...  I ll try to adjust the aerobars a bit and see if that helps.

*** I ll post some pictures after my ride... ***

I move forward on the saddle too when in aero but it feels natural and comfortable and more powerful. I don't consider it a problem.
I have had a professional fit (road bike with a ff seat post and clip on aero bars), but have made some modifications to the bike and fit since then. I added bull horns and bar end shifters/brake levers, moved the stem down 5mm, moved the aero bars a bit fwd, and widened them a bit. Feels good to me.

OK,

I actually spun the seat post around backwards, and was able to adjust the saddle forward about an inch... that problem was solved... sort of.  I still slid forward, so now I was almost off the seat.  I did ALSO move the aerobars back.  My arms and shoulders really hurt a lot.  It was like I was using my arms to hold myself back on the saddle instead of being stationary and leaning over to grab the bars.   As soon as I got home I switched the bars back.  I ll give the saddle another go with the bars in the originoal position.

Rode a hilly 17 miles in about 50 min.  I was not pushing it too much, but I got those calf cramps again and my quads were burning.  I was definatly hydrated.  You just have to take my word for it.  A friend of mine suggested calcium... we will see if more milk helps. 

I tried to get some photos posted, but I can't figure out how to re-size them to fit.  I ll keep trying...

without seeing the bike fit not much i can say there other than i slide forward when really pushing it too.

on the legs burning, its not a leg strength issues at all, but rathere a fitness issue. you dont really need strong legs are all to be fast, jsut the conditioning to hold onto that pace longer.
