The Epson Runsense SF-510 is a GPS runners watch with in-built stride sensor reviewed and tested by Tristan Haskins. Please note… at the time of writing this we have only personally tested the TOP of the range SF-810. This SF-510 is the second model up from a line up of 4 products in Epson’s Runsense range. The SF-510 takes the SF-310 and adds to it an internal STRIDE SENSOR. This sensor adds stride length, pitch (strides per minute) and will continue monitoring your running speed & distance in the event of GPS signal loss (under trees or indoors etc). If you want heart rate monitoring you will also need the optional HRM chest strap (or any Bluetooth 4.0 HR sensor).

Accurately keep track

This accurate and intelligent GPS sports monitor features smart device compatibility. Sync the SF-510 with your phone to enable fast GPS positioning with the AGPS function to get you on your run faster. Its Smart Stride Sensor measures stride length and pitch and learns your individual technique, so if GPS signal is lost, the SF-510 will keep track of your distance and pace.

Helping you to train smarter

Runsense lets you track your progress against long-term targets and view your estimated finishing time or distance based on a set target, or you can improve your performance with the interval training mode. The free Runsense View portal and Run Connect app1 help you customise your settings, and monitor, analyse, compare and even share your stats to maximise your potential. Connect to your smart device using Bluetooth Smart. Cycle through four customisable screens, with up to three measurements on each, chosen from huge range of options.

Train your way, for longer

Its active GPS battery life of 30 hours – up to three times longer than comparable competitor products2 – means you can run for longer before having to recharge. Water resistant up to 5ATM, and with a compact, lightweight design, the SF-510 is designed to fit into your lifestyle. Use it with an optional heart rate chest strap, or use the indoor mode to track your run during indoor training.
