6.55K Run

Today I set out to run 6K but ended up running 6.55K!  I ran it in 1hr and 7mins, a little slower then I had hoped.  Has anyone had any issues with the bottles in their Nathan Hydration belt leaking?  I used by belt today for only the second time and notice the bottles leaked quite a bit.  I was suppose to run 5K tomorrow but now I am going to have to work late.  I will have to postpone that run until Thursday now.  I am still having issues with heart burn.  I do have a doctor's appointment on Thursday so hopefully he will be able to offer me a solution for the heart burn that has plagued me for the last couple days.
