Shiver me timbers- 325 days to go

There comes a time in every man's life when he must conceed the fight. Not give up the war, but change his

strategy to win the battle. For me, the second week in December was that time. It was so cold, that I was riding with winter cloves on. I had to stop at the half way mark (15 miles) to warm up my toes. The temperature was 37 degrees & I could not feel my face. Normally, this is the point in the year where I stop riding.
Just one problem...I couldn't take a four month break from cycling this year.
I was training for a race. A very long race.
Last year I started riding in April. By July I was riding 40 miles every Sunday. By August I was riding 60 miles every Sunday. This year my goal is to be at 60 miles by July and 100 miles by August. The only way to do that (without hurting myself) was to continue riding through out the year.
But how?
Even if I bundled up, snow would soon make cycling to dangerous.
Answer?
Take it indoors.
So every Sunday I do 30 miles at the gym on a stationary bike. Is it the same? Nope, but it should be enough. How can I be sure? Because it was done last year at the Ironman World Championships in Kona Hawaii. One of the two US Navy personnel to compete had trained on a stationary bike...in a submarine.
