Hey thanks for the response jfreaksho
I have kinda come to the conclusion that I may just be disappointing in the 'loss' of fitness. However, given the three week rest period it probably should be of no concern that jumping straight back into anaerobic exercise would not result in a noticeable performance loss. I will continue training and not modify my diet (except maybe bump up the Calories in through more fats and protein) and see how I perform in a week or so, after I have 'gotten back into it' - so to speak. Until then I will lower the intensity until I am back at my per-rest / per-course performance. However, given that it has nearly been 6 weeks of 'roughly Primal' (nearly 4 weeks of strict Paleo) I should be close to being over the transition period - I guess I will just have to monitor it closely.
The course itself is the 'Combat Fitness Leader' Course.
If anyone else has any comments or help that would be greatly appreciated (even similar experiences?)
