Answer:
The race through the desert was GRUELING ; it was too long and hot, and my shoes were too tight.
I had a great time with the CHALLENGING race that included an obstacle course section.
Completing the race was PROBLEMATIC because my shoelaces kept breaking, the road was slippery in places, and the sun was in my eyes.
The uphill section of the race was EXHAUSTING , and I felt that my legs would fall off and I wouldn't be able to keep going. However, I felt better on the way down.
