Thank you Cooker and no I'm not over doing it. I'm "listening" to my body and plan are doing it (biking) just 2 days a week for a while. I'm riding slowly (not to slowly)and if I see its too much I'm stopping for a while. I'm planning cool down spots and all. Lots of water!!! Today is my full day of commuting and I'm leaving the house extra early in case.......
Good for you! Let us know how the biking is working out.
