Volume Week
We are going into a volume week which means you will be doing more hours of training at a lower intensity. So with that being said lets start out the week with: 45 min. zone 1 rollerski or rollerblade this if you can Have a good one. A quick quote from How to, When to Why to: "The important seperation between distance training and interval training is that there should be a significant effort and heart rate difference. Some athletes are not able to go hard enough when doing time-trials and intervals because then have done their distance training at too hard of an intensity. This causes them to lack the energy needed to go hard."
