Well, I could actually do an impression of breaststroke and freestyle but I basically started from scratch 2 yrs ago, just around the same time of the year, so you can do it.

But you need to be dilligent to the point of obsession about technique work and have yourself be checked as often as possible by someone knowledgeable. Too many practice struggle instead of front crawl.

In fact I would do technique work almost exclusively. The first sprint won't be easy but it is just the beginning of a long friendship, right?
