Interval Training 600m x 5

In my last interval training, I thought that I should go for 400m x 8 in the next interval training. However, I decided to change it to 600m x 5 and have only 2 mins rest in between. This is a 50% more work that my last interval training (400m x 5). I also adjust my target pace to be 5:30 instead.



The 1st, 2nd and 4th, & 5th interval all contain some uphill slope in it. And I am happy that I can keep the average 5:30 pace. I will increase the workload again in my next week's interval training.
