Yup, I'm doing both of these things this year! [

] I feel SO good about this year, I cannot even tell you. This is going to be my year! Two of my goals are to run a marathon and hike Half Dome in Yosemite Park. I registered for the American Stroke Association marathon last Wednesday! I can run the half (13.1 miles) or the full (26.2 miles). It's in San Francisco on July 29th. I have to raise $2500.00 and $625.00 of that I have to have by March 28th. I will definitely be posting asking you all if you would like to donate. So you'll be hearing from me! I have a fundraising appointment with the director this weekend to outline my fundraising plan. [

] I am SO excited. I am nowhere near the shape I need to be in, but I'm gonna do it anyways!
Half Dome is another one and I'm more scared of this than the marathon.
"The hike is somewhat long (about 17 miles round trip), somewhat steep (about 5000 feet of elevation gain), and somewhat high in altitude (summit is 8842 feet above sea level). Fit hikers usually take 7 to 10 hours for the round trip. Less fit hikers can take 12 hours or more. "
So yeah, I'm scared. [

] I've always wanted to do this though and I know that I can. Everybody thinks I'm crazy for attempting either of these things, much less both of them in the same year.
Has anybody hiked something of this scale and/or run a marathon? Even if you haven't, what about just hiking in general or long distance running? I could really use some advice on how to train, particularly for the hike because with the marathon I will be training with coaches. Any advice, thoughts or just support [

] would be greatly appreciated.
Wish me luck guys! I start training for the marathon tonight!
