Hi Chris and welcome  

What track system are you using? There are plenty of options - also depends on what lap counting software you are planning to use.

For solo running, I find smart phone apps like LapTrax (Android) and LapTracker-Auto Timer (Apple) are really handy. They use the camera on the phone to sense movement in a defined area. They do need some careful setting up and calibration, but work a treat.
