I'm crazy about day hiking every since I started 2 years ago. My first hike was Rainbow Falls up to Mt. LeConte in the Smokies. Since then I've usually done hikes of no more than 13 miles in one day. This year I was able to tackle a 26 mile hike going up to Thunderhead and Rocky Top Mountains making a complete loop. It took 12.5 hours but it was really fun and worth it. Next year I would like to shoot for a 35 mile hike in one single day. What's the longest hike you've done in one day?
