Not counting races with slower family members where I will be the pacer, planning on a 5k, 10k and half marathon in 2014. I find races hard on my body (soft tissue) and I do not enjoy to go flat out for that reason. I do well in my age group, but certainly not better than the guys 20 years younger than me. Sometimes I get passed by a geriatric person. That puts me in my spot but also gives me hope.
Have fun running.
