Having raced long cycling events in the cold rain,
Long snowshoe events in serious sub zero temps,
Reallllly long kayak races in terrible weather,
And long running events in cold rain and wind...
There is no comparison at all
The running is most atrocious.
You create more heat and are at the redline longer in a running event, and if you are off on the layers you immediately overheat., or are chilled. You cannot effectively dress for the weather in Boston....
Hats off to the finishers, it was brutal.
