And the deal is on!

I haven't been working out properly for almost two weeks now and according to me, that is much. I really need my exercise to feel good and happy so it means a whole lot to me. And the funny thing is that when I fall out for one or another reason (this time my back) I have such a hard time getting back again.
This time it's even harder because I haven't paid for any longer than May for my muay thai lessons so I can't go back to that. I will change muay thai gym for a reason that I will tell you about later.Anyway. I have my Roller Derby and the gym at work but to really get going again I've decided to attend two running events in June. And after each run fulfilled I will reward myself.

• The first run is 5km at June the 8th. I must run faster than 30 min. And I will reward myself with these shoes!
• The second run is 10km at June the 19th. I should do it in less than an hour. If I do, I will reward myself with these shoes!
  

I think this will get me motivated and when I fulfilled those goals I will focus on running a little bit faster. I've been thinking about heart monitored running as well but it seems to be a little bit overkill? Or what are you saying?
