Does my bum look big in these?

In two months I have clocked over 400 kilometers on my bike. It's true. My odometer says so. During this time I have increased my endurance and strength without the harsh impact on my joints that can often come with running. But have I increased in other areas too?

The majority of those kilometers are made up of my rides to and from work.It was after riding to work one morning that a colleague said she would never take up riding because it gives you "a fat butt and huge throbbing man quads". Now, even though I have not always had a road bike I have for years taken spin/rpm classes. If it gave me a big butt or big vein covered legs like some steroid soaked body builder or Tour de France rider then I would have stopped.  What's funny is that my pants HAVE been a little tighter lately, however, I can almost guarantee that comes down to the tub of ice cream and family sized portion of ginger slice I ate last week, not because I have been cycling more.

During one of our training rides Mr Triathlete stopped for a photo op. I now give you permission to look at my butt. I don't think cycling has given me quads that belong on the world's strongest man competition, but I want you to be the judge- is my butt looking big?
