You land on your feet at the bottom red line, both your legs break. You slide off the bottom red line cliff, and bounce off some trees at the bottom. Hopefully this knocks you out, but we're going worst case. You break a few more bones, ribs or something, one punctures a lung. Adrenaline works its magic for a little, and allows you to crawl forward. Though the trauma is so severe, that your body begins to shut down. Some time later you die as a result of catastrophic injuries. if you do it when nobody is around, you are unlikely to be found and rushed to the hospital. So my worst case scenario, you die, but it's a much more painful death than you had originally hoped. i guess the actual worst, is that you somehow survive.
