I have been riding after work 30 miles after work each day. It is about the same distance to work and back in a relatively rural area in texas. I have a bad head on my car now and access to a car and motorcycle but I'm just irritated and think I would better use my time riding to work and back and then still try and do group rides to get in better shape.

I live in Wichita Falls TX, we are in a drought and it barely rains. So I am going to "skimp" on rain gear for the time being but will add it as I can afford it.

Logistics:

I have a GT Transeo ultra hybrid with 28c roadish tires and a Giant Defy 1. The GT I can average about 18-19mph and the Giant 19-20mph. I can ride the GT 30 miles no problem and the Giant 50ish miles is getting near my limit on it. I ordered a tubus fly bike rack (big feet and dont want to hit the rack) and a top peak RX TrunkBag EX.

What I don't need:
I can leave jeans, shoes, deoderant, soap for showering, and most of my food at work (Mainly pbj's and fruits I eat or go out to eat nearby).
I also have a toolkit I can switch between bikes on a seat mount and carry a spare tube, should probably up this to two for work.

What I need:
Underwear
Socks since ones I wear in will be moist
Shirt
Towel? Not sure here what I really need

What recommendations does everyone have for me before I start doing this? Thank you!
