>>1582443>only 44.6 feet of elevation gain per mile on averageThat's far from impossible and a decently conditioned amateur rider can attain that, especially if there's plenty of descending on the back half of that ride.

To that effect you should delete this thread if possible and refrain from posting similar threads in the future.
Good day, sir.
