•Keep 4'
between you and the person in front of you - if you fall, you won't take him/her down -
if he/she falls,
you won't trip over him/her.
And you won’t get
whacked by a branch.
•Expect to
get mentally tired during the run - from focusing on where you plant your feet with every step.
•Expect to
be physically tired after the run - plan for a nap. Expect
to be sore the next day.
•If/when
you fall or roll your ankle, expect even more soreness (upper body from impact, along side of leg from stretching that muscle due to an ankle roll).
