I've gone for 20 / 30 mile trips (hands get numb). Just make sure you have a buddy or someone you can call to come pick you up as an absolute last resort. I always bring with me the tools needed to fix the most common issues ( all sizes wrench, allen keys, etc, an extra chain and master link as well as standard tools like vice grips, pliers, flat head / phillips screw drivers etc). Although I've gotten lucky and my very first build hasn't left me stranded yet. At least 600 miles or so and the only thing I've had to replace is the tensioner bearing (I have the case mounted spring loaded style).
