I've been training since May, working towards a century. I decided a while ago I would do my century at the Blue Water Ramble (in MI) which is Oct. 1st. I chose that date because it's the end of the season and I wanted to give myself lots of time. Well, I'm getting nervous about the weather. I do not like to ride in cold, windy weather and I'm afraid of the possibility of that day being just that. I am doing a ride this Saturday - the Celebration of Cycling. I had intended on doing the 75, but wondered if I should go ahead and do the 100 because the forecast is 79 and sunny (my ideal riding weather). The furthest I've ridden is 70 miles (just this past Saturday). It was a cold, windy day and I felt like I got hit by a truck when I was done, but I did the 70 miles.

Anyway, I'm wondering if it's too big of a jump to go from 70 to 100? I've been riding 3 times a week (sometimes 4) since May, adding 10 percent to my distances every week (with occasional breaks). My average speed for my longer rides is 16-17 MPH. I feel pretty confident that I can do it, but have a little concern because every time I increase my mileage by 5-6 miles, I feel it! I don't know if it's mental, but I've had a couple of rides where I wasn't sure I was going to make it back because my body was so tired and achey.

Comments? Suggestions? I appreciate any insight!
