Unicycling after 50

By chance, my progression in my unicycling “journey” has brought me to the point where I believe I may be ready to attempt this online unicycling Challenge.

Hill climbing by unicycle the height of the tallest mountain in the solar system in the next 3 months.
Olympus Mons (height 21500m / 70538ft)

The event app has set other mountain’s heights as milestones.

I have a “plan”, and a 6.8kg 29" unicycle with 127mm cranks.
My 56th birthday is in March.
