We have three Primary Lines. One for sprints (races under three hours), one for long distance (races over ten hours) and one for the middle distances (typically five to eight hours which are usually the 250 to 400 mile races).
These primary lines descend from a number of Foundation Lines that were used to found our loft. Some of these we still maintain and will continue to do so as long as they are contributing to the development of our Primary Lines.
We also maintain a number of Heirloom Lines - families that we have found to possess unique and valuable genetics that we feel need to be preserved. Some of them are behind our primary lines while others are maintained to keep available a strong and diverse gene pool for use in the future evolution of our lines.
No breeding program can stand still and expect to remain competitive in this sport. We are continuously evaluating new lines. These are our Trial Lines.
