Do it. I used to worry about clothing and being sweaty. I gently roll my dress slacks, shirt and tie. I towel off sweat. After cool down, I put on my tie. Others were very curious at first. Now many are jealous. They envy my cost savings and the fact I get two work outs a day without trying.
It gets easier with experience. Dress comfortably. Get the gear you need to make the commute easy for you. Soon you will look forward to your commute.
