Do I need to carry a backpack or a waist hydration system with obligatory equipment during the race?

No. The race regulations do not demand obligatory equipment of any kind. However, it is advisable that athletes who follow a slower pace should carry a backpack with the basics (windproof jacket , cap, sunglasses) as well as liquids and food to cover their increased needs for the race. All faster runners should not worry because there will be numerous Refreshment Stations every 20-30 min. (for slower runners every 50-60 min.)
