Trying to do a century on one ride without any kind of break is hard! Closest I have come is 87 miles doing 50 miles earlier in the day and 37 miles in the evening. First 30 miles I can do easy at a 20mph pace, but every 10 miles after that I get slower and slower and seem to exponentially require more liquids to stay cool and hydrated, especially in 90° heat with the sun beating down on you. After 50 miles my arms and back start to hurt and my speeds are reduced to almost single digits.

With that being said a century can be done without training, but it is going to be very taxing on the body and take a good chunk of time out of your day. More training will make it more effortless, at least I hope so. 60 miles is the best I can do at one time. I am going to try for a century again when it is much cooler outside.
