Good for you ShoMeRacing! That seems to be a lot of weight to lose in 1.5 months, undoubtedly diet and exercise, huh. Stay motivated and keep on pedaling, you'll get there, no problem. Your program is working much better than mine. Part of my program is riding 10 miles to my favorite cafe for biscuits and gravy and back.
I am curious, have you done or do you plan to do a multi-day tour on the Katy? Though not a taxing ride, it's a fun way to log miles and miles of saddle time. Perfect for a light weight credit card touring. The Ride Across Kansas and the MS 150 sound interesting, that should give you a good idea of where you stand for your coast to coast tour.
Thanks for the post, many great responses for consideration. Keep us posted on how the training is going. Good luck!
