Training for a 5K can be stressful and draining. One way to mitigate that is to find a training buddy or group. You can keep one another accountable to the schedule and training regimen, and offer much-needed encouragement when things start to look insurmountable.
If you have a friend who already runs, that's a great place to start. He or she can be both a cheerleader and coach as you make your way through the training. Otherwise, look for a local club or running group to hook up with. Check with area gyms, the local YMCA or a community center to find a group.
