The Epson Runsense SF-810 is the top of the line in the Runsense series, yet is still an affordable lightweight watch promoted by runners. It features GPS and heart rate monitoring functions and is designed to maximize your running routine. It measures heart rate and other analytical statistics from the convenience of your wrist, which helps you track, evaluate and increase overall run performance.
The Runsense automatically records your speed, length of stride, GPS location and heart rate levels via the sensor on the backside of the watch. The philosophy is that by computing all this raw data and analyzing it through the free Run Connect mobile app on a routine basis, you’ll ultimately become an improved runner.

While the Runsense SF-810 is capable of tracking stats for a variety of activities such as running, biking, hiking, or general cardiovascular training it is suited best for runners. The Runsense SF-810 is waterproof to 50m and can be used during swimming, but the GPS and heart rate features will be inaccurate if they work at all.

The Runsense 810 acquired heart rate quickly and the reported data was very accurate, but during intense running drills, it regularly showed a discrepancy of 5-10 BPM. Overall the Runsense 810 had a better than average calculation when compared to other heart rate monitors.
The big issue with the SF-810 was not the accuracy of the GPS data, the one feature these watches are purchased for, which is highly accurate, but with the amount of wasted time waiting to acquire the GPS signal. Despite the connecting time to a satellite, there was a noticeable distinction in time and accuracy of tracking compared to more expensive GPS watches. It typically was less than a tenth of a mile off even during longer runs, which is a far superior margin of error for a GPS device.
The Runsense View Portal allows you to store your training data online and offers a suite of analysis tools. The Dashboard View in the Run Connect app is, however, poorly mobile-optimized. You are able to see a calendar with the dates you trained, as well as results from each session, including heart rate, a map of your route, elevation and your pace. However, on most smartphones, the icons and script is small and challenging to read sometimes. Plus the Bluetooth capability is lackluster at best. It’s better to connect through your computer after you get home.
To connect at home, you get to tackle the block of a charger. However, I essentially liked it if I was at home. The watch fastens in the charger securely and you never have to work it around to get a read like some other watches that come with a charging clip. But, if you are traveling, the extra mass tends to be a bit of a nuisance.
The Epson Runsense SF-810 is compatible with the free Run Connect mobile app, but it is pretty basic in design. It is, however, easy to transfer and analyze your data through other favorite running apps such as Strava™ Runkeeper or MapMyRun. This has been recommending in more than a few reviews.
That said, what runners sacrifice in a quality appearance, they will benefit from the compact and lightweight feeling during longer outings. At just 52g the Runsense is barely perceptible on your wrist, which makes it ideal for runners or sporting around town for casual activities.
On the favorable side, the Runsense SF-810 is waterproof to 5ATM (50m). After a couple of outings in light showers; it held up well and should manage fine if you're out competing during a thunderstorm.
Once you have it set up, though, the watch functions without much effort. It works equally well whether you’re outside or on a treadmill. The app that ties into the Epson Runsense SF-810 is essential and a lackluster, but it’s compatible with other running apps, which improves things significantly. In general, it’s well made, easy to use once it is set up and can assist you in becoming a better runner, but does have some weaknesses.
The display has a low-resolution dot-matrix design and can be difficult to read in dim light or bright sunlight, and the amount of data crowded on the smaller screen could be a challenge when running at a good pace.
The one upside to the beast of a charger is that the watch does clip securely in place, ensuring the watch gets a strong charge unlike some of the clip chargers.
Not sure if syncing using Bluetooth would be faster for data transfer, but it would be careful not to have to travel with a large chunk of plastic to charge my lightweight running watch.
