Does tapioca syrup supply long-term energy for endurance sports?

Yes, tapioca syrup is a mixture of simple sugars and more complex carbohydrates.  During endurance sports, the body typically processes the simple sugars first for immediate energy and then slowly processes the more complex carbohydrates, giving intermediate and long-term energy, depending on the type of carbohydrate.  Different syrups provide varying profiles of immediate, intermediate, and long-term energy.
