How many years over 50? What is your weight, gender, present fitness level and training status.
I could still run a 1.19 at 50, however at 53 I am now only managing 1.24 at present. (I was 1.15 at 47). After 50 it is more difficult to predict times, the body cannot take the same effort required in training. It is really important to include rest days in one's schedule, it is better to set 1 mile target times and stick to them i.e. 8 mins very mile etc. The most elementary error to make is to not do the training and too start off too quickly.
Best of luck in your challenge, a time of under 2 hours would be considered to be acceptable and suitably challenging and would require 9 minutes per mile.

Considering that only about 500K people have ever run the Boston Marathon in over 115 years, the answer is not very many. If we're looking at just the US population, then that would be less than 0.2% of all Americans will run in the Boston Marathon. If we're looking at worldwide population, then it would be less than 0.0001% of the world will run in the Boston Marathon.
Earnings over an individual's lifetime or times for running a half-marathon over a lifetime

The average value of an a.c. voltage or current, over a complete cycle, is zero. For this reason, the average value is normally quoted over a half cycle and, for a sinusoidal waveform, is equal to 0.637 Vmax or 0.637 Imax.
The average speed of the world record time is slightly over 20 km per hour, which is around 1 km per 3 minutes.
It starts at the beginning & ends when it's over
Any Swim/Bike/Run Race is considered a Triathlon. I believe this is a reference to the Half Ironman Triathlon. This is a 70.3 miles race, consisting of 1.2 mile swim, 56 mile bike, and a 13.1 mile (Half Marathon) run.
Dude, you're just doomed.
