my stretch marks getting wider because of excessive cycling??

Hey Ladies:)
I am cycling regularly for 4 years. Actually mountain bike...I try to cycle with lighter gear whenever it gets harder uphill but anyway a lot of times i feel i am burning out myself to come to top. Last months i recognized that my stretch marks that i got when i was 16-17 are getting wider and wider just behind my knees. I am not getting weight or losing..I am not using any drugs...I use creams regularly and i drink a lot of water . I eat healthy...I say to my husband that i feel my saddle is too high but he says it is even a cm too low. He also thinks i am making this up about stretch marks. But the directions where they get wider seems like cycling has someting to do with it...Has anybody any idea..?:confused:
Ooo..and sorry for my terrible english...:o

stretch marks (and other scars) tend to widen and flatten out as you get older. Moles get bigger too. Your skin becomes less elastic. :rolleyes:
Cycling has nothing to do with it.
I'm sure you have not tripped the "excessive cycling" alarm yet. :)

:D Hope not...I enjoy cycling so much....:(

You know, it could just be that the rider is shrinking and the marks are staying the same...

Hmmm..Shrinking...I am 28...Too old already ha:(

she meant shrinking in a good way! like losing excess weight!

ok:o

I have read somewhere that its best to make 90 turns a minute if u want to keep tha muscular volume the same.Maybe i should do so not to expand them more...

If anyone has any suggestions,alll welcomed:)
Thank u very much everybody...
