Your physical description does not worry me... what worries me is that you aren't thinking that you can do it.

Look, half of our physical abilities comes from what goes on between our ears. The other half is what kind of shape we are in, and the training we put into our goals.

You have a month. That is plenty of time to get ready for 35 miles. Ride 3-4 days a week. Start small, maybe 10 miles a day... go from there.

Remember, you can stop and rest... during your training month and when you go to ride your 35 miles.

Once you get a "training schedule" mapped out... sit down and tell yourself that you are strong and that you can do it. When you are riding and you feel tired... set a goal (I will ride for 5 more minutes) and reach it. Also tell yourself, "I have strong thighs, I can do this!".

Have a positive attitude about your physical abilities... and train for your goal. With proper planning and mind set, you can achieve your goal!
