How to commute to work on your bike and dress up
I've recently started commuting to work 3 times a week and my commute is about 8 miles each way. I've found if I roll my clothes rather than fold them and pack just before I leave, there are no creases when I get to work. I always put my shoes at the bottom of my bag, then trousers rolled up then shirt. I leave my ties in my desk draw and leave my suit jacket at work.

It takes me about 45 minutes to get to work and I make sure I take the last mile easy so I don't arrive out of breath. I then spend about 10 minutes in my cycling clothes (making sure the kettle is boiled and quickly checking emails) to give me time to "cool down" before I go and get changed in to my work clothes. I've found I'm completely "dry" by then but if not I use wet wipes. Liberal use of deodorant and I'm good to go.

On the way home I just do the reverse. I attack the route home faster for a work out as I can have a shower when I get home.

I believe that as you get fitter you'll sweat less too, so it gets easier.
