Hi everyone, this is my first post on this forum.

I got into road biking about 5 weeks ago. My current bike is a Schwinn Varsity Flat Bar (weighs about 30lbs, 200$ in Walmart) that I borrowed from a friend.

I started biking in Silver Comet Trail, Georgia and last week I completed it totaling about 130 miles in 10-11 hours. My maximum before that was 60 miles.

Now I am planning on completing 200 miles in a single day ( about Silver Comet Trail+Chief Ladiga Trail ). Do I need to focus mainly on upgrading my equipment or my training? I am slightly overweight (5-11 190lbs) but have a pretty good stamina and can run half-marathons everyday.

Any type of advice is welcome ( Biking technique, diet, time&planning). I will also be glad if you can show me a guideline of a proper training plan.
