Training & Nutrition - Yet another century question

My longest ride to date was in Sepember when I did the 75 mile variety of the Old Kentucky Home Tour. It was pretty demanding.

Now I'd like to do the Horsey Hundred on Memorial Day. If I read the stats correctly it' a much flatter course. However, between the artic temperatures and some illness I've had precious little training time this year.

What do you think? Doable? I'm 57 and in decent but not great shape.

It is all about holding a determined pace.

It is not a race.
Just try to determine a pace and hold to it, no matter if you want to go faster hold yourself back.

Hey, you have lots of time. I managed to get myself two skiing injuries this year, so I couldn't start training until Feb. 1. I'm planning on a 100K at the end of the month and a 200K in late March. It's gonna hurt, but I should be OK. Main thing is to ride at least some every day.

Isn't Memorial Day in late May, 3+ months away?

Go ride ... gradually build up. You should be fine.

It's doable fer sher. Get out there and train. It's more of a mental challenge than physical. If you have the mental attitude and train as necessary, the physical condition will come.
I'm 66, been cycling for about 5 years, and I've done the Mulholland Challenge the past 2 years and am looking forward to it this year.
Go frit, Link

If you did 75 miles already, then a century should be doable for sure.
Just like everyone says: ride at a manageable pace, make sure you take care of the nutrition/hydration, take some small breaks every now and then, and ofcourse Go ride.
