Calculated for your horse's exact profile
Thoroughbreds were bred for speed, not warmth. Their skin is thinner, their coat is finer, and they carry less natural body fat than native breeds. This means their Lower Critical Temperature (LCT) — the point at which they start burning energy just to stay warm — is significantly higher than a Warmblood or a native pony.
An unclipped Thoroughbred typically starts feeling the cold at around 8–10°C. A clipped Thoroughbred can need rugging from as warm as 14–16°C.
Compare that to a Warmblood (LCT around 5°C unclipped) or a native pony (LCT as low as 0°C) and you can see why a one-size-fits-all rug guide doesn't work.

These are starting points only. Your individual horse may need adjustment based on body condition, shelter, and their own thermoregulation. Rugged Up calculates this for your horse specifically.
Most horse owners rug based on what feels cold to them — not what's actually happening at the property at 2am. The coldest point of the night is usually between 3–5am, well after most owners have gone to bed.
A Thoroughbred left in a 200g rug when the overnight temperature drops to 3°C with 25km/h winds is effectively feeling sub-zero conditions.
This is exactly what Rugged Up solves. It pulls real-time and forecast weather for your horse's exact GPS location — not the nearest town — and factors in your horse's breed, clip type, age, and body condition to give you a recommendation for morning, day, evening, and overnight slots.

Cold snap alert — overnight low 3°C
Wind chill to −1°C. Consider upping to 300g for your Thoroughbred.
Shivering or muscle trembling
Tucked-up stance (hunched back, tail clamped)
Reluctance to move away from shelter
Feeling cold to the touch behind the ears, on the back, or at the flanks
Weight loss despite adequate feed
Poor coat condition
If you're seeing any of these regularly, your Thoroughbred is likely under-rugged for overnight conditions. The fix isn't always a heavier rug — sometimes it's about timing (rug change at dusk, not sunset) or adding a neck cover in windy conditions.
