I'm hoping to complete at least 61 miles in my first century. I'm not sure bringing my bike will be feasible. Days are usually 10-12 hours long and I don't want to risk losing my bike if I have to jump to an earlier flight (that happens at least 80% of the time).

I'm very fit and will usually run or spin in the absence of outdoor cycling. I'm hoping a recumbent bike or treadmill found in most hotels will help keep my base training up but I'm not sure if it will help outdoor cycling. I'm hoping that it will.
