I'm a fairly experienced runner. Done 30+ HM, one full marathon and numerous shorter races. Race on average once a month. I take my running seriously and do pretty well in my age group with the occasional trophy.
I do parkrun most weeks and after having to have 5 weeks out due to illness at the end of last year am more or less back to where I was 18 months ago. All my best pr times and been "naked" without a watch, when I've just run the best I could by feel without worrying about the time/pace. I've run some good 10Ks that way too.
I'm doing a HM tomorrow (volunteering at pr today!). I'm wondering if I'm brave enough to try the HM without a watch. I feel in good shape, it's a fast course and I hope to do a good time. Usually in a HM I use the watch to make sure I don't go too fast in the early stages and to give me that push at the end if I'm close to the time I want. I'm wondering if it hinders more than helps and I should run without it, but am I brave enough to give it a go? If I mess up the pacing completely I'll be very disappointed as I do feel this could be "my" race.
