I am in my 1st season of triathlons, done 2 sprints with 2 more to go in mid & late august. I started training in May and am a MOPer.

Seeing as my last 2 races are quickly approaching can i throw out my long slow runs and long slow rides and incorportate a higher HR or speed into my last 3-4 weeks of training?

The last thing i want to do now is do a long workout at a low HR - its boring and i dont see how its helping for the upcoming races. I just want to do everything i can to cut my times down as much as i can for these next two races.

I have about 5-8 hrs per week to spend training and am shooting for 2 runs, 2 bikes and 3-4 swims per week. (a long bike for me is 2hrs - i ride a mtn bike)

is there anything wrong with running at a 5k /10k race pace for my training runs?

thanks
