8xmile tempo intervals

Today I was still feeling a little under the weather but able to run . I wanted to do a 3x2 mile tempo but wanted to do it on a flat surface . So I decided to stay in the house on the treadmill . Started out @5:29 pace but wasn't feeling it . Decided to break it down into mile intervals . After the 3rd one I was feeling great and worked the pace down to a 5:20 . I ended up doing 8xmile @5:20 with 1:30-1:40 recovery . Think I could have done it a little faster but didn't wanna overdo it . Next tempo workout will be an 8 Miler .
