The Shires Running Maringale Is Made Out Of Beautiful Quality Salisbury Leather That Is Characterised By The Stitching Detail. The Shires Running Martingale Consists Of A Strap That Is Attached To The Girth And Passes Between The Horse'S Front Legs Before Dividing Into Two Pieces. At The End Of Each Of These Straps Is A Small Metal Ring Through Which The Reins Pass. It Is Held In The Correct Position By A Neck Strap. A Correctly Adjusted Running Martingale Is Fitted So That Each Of The Forks Has About An Inch Of Slack When The Horse Holds Its Head In The Normal Position When Correctly Positioned, The Reins Make A Straight Line From The Rider'S Hand To The Bit Ring When The Horse'S Head In At The Correct Height And The Running Martingale Is Not In Effect. When The Horse Raises Its Head Above The Desired Point, The Running Martingale Adds Leverage Through The Reins To The Bit On The Bars Of The Horse'S Mouth. The Leverage Created By This Pressure Encourages The Horse To Lower Its Head. A Running Martingale Provides More Freedom For The Horse Than A Standing Martingale, But If Fitted Incorrectly Can Cause Severe Pressure On The Horse'S Mouth.
