Ok, if you were afraid of the pain you wouldnt be riding a bike!!! LOL, I went 6 miles and my female parts are killing me. I cant wrap my brain around 56 miles!!! I am sure Danni will chime in about the mental thing, but look at where you have come from!!! I am going to actually try to run , OMG, I just typed run...a 5K tomorrow. My goal is dualtholns, but we are talking about you

......I am guessing the worst part will be the rollers. Is there a way you can program your music to have uplifting music hit when the rollers occur? How long will it take you to do this? Maybe you could preplan a break so you dont feel like you are pooping out or quiting. Also, one thing I do, it remember to be greatful when you are hurting the worst.....when I think I am about to die on the treadmill, track, elliptical whatever, I think about where I was a year ago. I am so thankful for my tool and the blessings of health I have received because of it....I can usually grin through the pain. Does that make sense???
I am so impressed with your journey and what you are attempting to do!!! Yeah, its gonna hurt, but its also gonna feel REALLY good!!!! I will be sending thoughts and prayers your direction!!!
