>To qualify to "run Boston", you have to run another marathon in a qualifying time
just to add this to the mix: there are faster and slower marathon courses, so you can improve your qualifying time by running in one of them. "downhill" seems to be a promising factor.
You’re not running down Helvellyn, it’s more the cumulative downhill that qualifies a “downhill” marathon. Remember this is 1500 feet drop over the course of 26 miles, so you’ll get the benefit of gravity without the downsides of steep drops.
