I've never been a huge "giver upper" for Lent. I would much rather focus on doing this that make me a better Christian and a better person. This year I am running everyday for Lent. This will help me to reach my yearly mileage goal of 300, help me to prepare for my half-marathon in May, help me to continue on my weight loss journey, and force me to take some time for myself.
My training plan has me running 4 times a week, so on my "off" days I am running st least 1 mile, but doing it without a timer and without my iPod. I am running in silence and alone (hopefully without the stroller) and using the time for reflection.
I've encouraged others to do this, or some variety of this, by adding something instead of giving something up, my challenge is on Daily Mile, and you can follow my progress there and here, as i plan to recap each Sunday.
