I've never really set goals as far as exercise itself, but I like to train for long bike rides. This year I joined a gym so I could use the shower before going to work and during the winter I started doing some cardio/weights and think I will continue.
But I'm really just love to build up to long rides. Two years ago I did 110 in a day, I'm thinking I'd like to break 125/150 this summer.
I'm fortunate I can get some biking whilst commuting. Currently, I am kid car pooling and I'm only getting about 1 ride in mid week, but come this June it's going to be 3-4 week 15 miles each way. That will certainly build my stamina in a month or two and just get some big rides in on the weekends
DC does a lot of things kinda meh, but the bike trail system is just the bees-knees. I've ridden 1000's of miles with only crossing a few roads. My commute to work is nearly car free from S. Arlington to Bethesda.
I can't tell you how relaxing that is compared to driving to/home work
Also as it's obvious, I'm a rabid music fan, but I never listen to music when I ride. The serenity of the trails is like gospel.
I ran when I was younger and loved it, but after my mid 20's it just hurt and didn't appeal to me anymore.
I will say that for every 100 runners on the trail, I only see 2 or 3 with a smile or are relaxed and enjoying their run...that I really don't understand. The other 98 look like they are in pain and not enjoying themselves.
