I'm teetering between doing 85 miles and 100 miles on an organized ride this weekend. I've never done 100 miles before, but I really would like to accomplish that sometime... and I see this as a great opportunity.

The longest ride I have ever done in my lifetime is also around 85 miles (day 1 of MS 150), and the two longest rides I have done THIS season is 67 miles 3 weeks ago, and 75 miles last week.

Doing 100 miles would mean a 33% increase in mileage from the week before - although I have been resting a lot this week. Whereas doing 85 miles would only be a 13% increase from the previous week.

No bike fit issues over 75 miles despite going out too fast and getting dropped at 50 miles, and this time I am promising myself that I will pace myself and not go too crazy in the beginning.

What do you think, 85 or 100? I keep going back and forth.

No better way to do a 100 than actually doing 100. Just get it done and put that under your belt. Screw the percentages, pace yourself and do it already.

Dude, go for it!

If you've done a 75 mile ride this week, then you are ready for 100. Definitely.

You need to be smart about it (i.e. don't start too fast, eat, drink), but you are ready.

As far as 85 or 100, Forget the 85. Do 100. You are ready.

What he said. If you did 75 miles last week, what's another 25? That's less that 2 extra hours on the bike even if you are going as slow as 15mph. Pace yourself and it should be a piece of cake.

3 unanimous responses already. Ok, 100 it is! I'll report back Sunday night. Thanks

I'll make it unanimouser. It's just one more break and one more leg than your 75-miler. Or take as many breaks as you need. You should be fine.

A 100 mile organized ride is easier than a 75 mile solo ride. (terrain being roughly equal of course)

+whatever Do it. Just go a bit slower, pace yourself, and enjoy. It shouldn't be a problem at all for you and even less of one as a supported group. Have fun!!!

once you have done a 60+ mile ride, the longer distances just take longer. that's all...at least that was my realization after my first century.

You should be fine. Go for it.

Congrats. Most people who post math on the 41 need it corrected. Refreshing.

Actually, you're in a WAY better position that that other guy in that other thread. :O

Pace yourself and have fun! Looking forward to the ride report!

It was a real doozy. If you're interested in my ride report:
