I'm laughing at myself. I was perusing that plan for intervals and I misread it. I am not at all fluent at bicycle lingo. Suffice to say, I worked harder than intended but I'm smarter for it.

Crankin, you and I sound somewhat similar. I'm 56. I like mastering distances and am not obsessed but want to get a little faster here. I did my 50 earlier and I want to do it again and the one I'm looking at would definitely be in hillier terrain. Eastern KS is relatively more hilly than central and western KS.

I just have not done any group riding (except for the charity ride in May). I tend to ride when it suits my schedule and at first I just felt too squirrelly on my road bike and like I shouldn't be around other riders.

I may have to--as my teacher friends say--be _intentional_ about sucking it up and doing a group ride offered by my LBS. I would get pushed and probably learn some improved bike handling skills.

Again, thanks TE friends. I really mull around in my head what I read here and I know I have learned things here.
