Last Saturday i made an attempt at a 300k rando. i've attempted that distance three times before. Only once was i able to complete the distance, but that time finished two hours over the time limit. i came to the realisation sometime around the seven and a half hour mark that i was not fit enough to face the coming hills and the rising heat. After turning around, i felt almost no pressure to make any kind of speed on the return trip, except that i really wanted to get back to Delavan before Brody Beef (-the best italian beef sandwich and fries north of the Illinois border,) closed. Didn't make it... sigh.
Still hoping to get a longer ride done sometime... the next 300 attempt will be next year. Meanwhile, i'll be content to plug away at 200's as perhaps the Slowest Randonneur in the Midwest.
