Out on the loop, you have to decide now.Heart rate, recovery and workload while you are still riding. Built for endurance, where the decision cannot wait until you are home.Heart rate, time, distance and energy, live on the loop.46%of the horses that started an elite endurance ride actually finished it. Nearly a third of all starters were stopped for lameness and one in ten for metabolic reasons. The signs were there before the vet gate.Nagy et al., 4,326 starts in nine countriesIf any of this sounds familiarHe looks fine, but looking fine is not a measurement.You do not want to be the rider who went one loop too far.At the gate everyone has an opinion about his recovery.The decision is yours either way. It is easier to make with his heart rate in front of you.Is he recovering, or am I pushing?At every vet stop you see his heart rate against the threshold and how fast it is coming down.Can he take another loop?Time spent in each heart-rate zone shows what the ride has already cost him.Do I have to stare at a phone?The figures that matter appear in HUD glasses or on your watch while you ride.Vet stopCurrent heart rate, the threshold, arrival time and the minutes since the loop ended.On your wristFull data on Garmin, the essentials and the alerts on Apple Watch.Your crew is looking at the same screen.At the gate they see the numbers you see, so decisions about pace stop being a conversation about how he looks. Afterwards you go through the whole ride together, loop by loop.What you needRequiredHorseCare Sensor Kit, €400Five sensors, charging stand, straps and back pocketRequiredHeart Rate sensor, €96Experimental version, sold separatelyAppiOS and AndroidFree for 90 days, then from €6 a monthThe rest of the systemHarmony in MotionSporting ConditionDynamics of TrainingMultivideo with TelemetryArena Tracking
