Hill intervals

Good to finally feel like I have my body back after been sick for 3 days. As I was to work on American time today I decided to do a short workout just after lunch instead of this afternoon and in order to still get a good workout I performed the first hill interval workout of the season.

Just 15 minutes from home there is a steep hill that I can climb in 4-5 minutes at max intensity. I will analyze the GPS data from http://www.sportstracklive.com/ later to see exactly how long I spend on each climb.

Now I understand why people say that hill intervals are painful. My legs was burning already at the top of the 3rd interval and by then I was considering not doing a 4th one. However I did finished 4 intervals and I managed to push myself substantially on the last ride up the hill so I feel quite good about today's workout. 

As said, I will analyze the data to get a better view of each interval in order to compare them to each other and also to track improvements over time.

Today's workout can be seen here:
