I am booked in to do the 100k Cheddar Cyclosportive on the 18th September.
Due to circumstances beyond my control I have done very little training for this event.
My longest solo ride this year was 2 weeks ago at a total distance of 41 miles.
The ride was fairly hilly and I averaged 16.8mph.
I mainly ride fixed wheel, my average ride will be 20-25 miles on fixed.

Do you think I will be ok for this ride. I am hoping to get out in the morning for 40-45 miles.

Just wondering if I have done enough training.... Your thoughts?
