I Really Don't Like the "real" outdoors, and I'd almost surely get killed riding my bike on the city streets, so something like an urban bikepath along the green parks and rivers of Columbus is perfect for me. The Upper half of the path runs north from Clintonville to Worthington Hills Park, while the Lower half run south from Clintonville to downtown at about West Broad Street. Personally, I'm a big fan of the Upper Olentangy multi-use trail. Though the closet entryway to the path to me is technically on the Lower half of the path, I basically ride the entire Upper path (+2/3 of a mile on the Lower) for exercise in the summer - it's about 15 miles to the trail head and back. It's pretty awesome. Just be sure to hydrate!
This part of the path is nice because there are only two spots where you have to ride on the road, and those are short distances in areas with little traffic (except crossing W. North Broadway). The path itself is paved and for the most part has two lanes so there is plenty of room for bicyclists, rollerbladers, dogwalkers, and joggers to go north and south without being in each others way. There is also an excellent mix of people on the trail, of all fitness levels, and for the most part, everyone is very friendly. Do watch out for the expert cyclist types in spandex though, as they can whiz by you and sometimes startle you if you're not paying attention. I usually ride during the day, because evenings *are* more crowded.
My only complaints about the trail are the distinct lack of water fountains and bike racks. I've noticed the water issue before but especially today because it was SO hot out. There are actually no water fountains on the trail... and there really should be - you know, the types you find in state parks and such. I usually end up drinking all my water by the time I get to Worthington and end up having to buy gatorade or water from the gas station at Worthington Hills Park. This is fine, but there was a biker wiped out on one part of the path (the police came, don't worry), and I couldn't help but wonder if it was from dehydration - because he didn't seem hurt otherwise (at least I hope not). And as for the bike racks - it would be really nice to lock up my bike in some spots and enjoy the many parks that you go through while on the path. Antrim Park does have one rusty old bike rack, but it would be nice to see more of them along the way.
Otherwise, I am very glad this trail exists. The 15 miles barely seem like anything in terms of exercise because it's so relaxing and frankly, "inside-my-own-head" time, but it's actually the same amt. of cardio I would do at the gym, if not more... and it's oh so nice in Ohio in the summer. :) read more
