This forum is the best interactive Q&A book you will find.

However, three books I identify as "must haves" from our "cycling libary"...

Cycling Past 50 - by Joe Friel (written in easy to read style, with lots of specific questions answered)

The Cyclists Training Bible - by Joe Friel (a bit more technical and focusing on training specifics and has guidelines for how to write your own training programme and prepare for events)

The Female Cyclist - by Gale Bernhardt (this draws on the Training Bible and the training bits refer often to that book - however, this has actual examples of training plans which you can adapt)

All three books include a female perspective - though obviously Bernhardt's book more-so than Friel's

Have fun doing your research.
