I have just started riding with intent this year. I am also a clyde trying to loose weight.

sore butt has been my biggest issue. I have a new saddle that has relieved pressure but put more pressure on my sit bones. I am thinking about a recumbant but they do not meet the weight requriments for me yet.

I would like to be able to train to the point of doing 100 miller every month. at this point the best i can do is metric century. With bike and camelbak i am 315 lbs.

ambient temp above 85. ( I like cool dry air for riding)
Heat index above body temp.
sore butt
no car to drive to an area with hills for training.
can't average more that 10 mph for two hours at this time ( Basic math, if i ride faster i can ride further in the time available)

I have no one to call, during the week, if i bonk or have a mechanical issue.
the one time i did take the car to ride a 100 miles I needed the county sherriff to haul me the last twenty miles back to the car. because it was dark and i had no lights
