Levels of insanity can be judged in miles.

For example, consider five miles the average distance the average human would choose to propel himself via sheer physical activity. A friend might say, "I biked five miles today," and you'd say "That's swell. Where are we going for lunch?"

If same friend said, "I ran 26.2 miles this morning," you'd probably exclaim praises for the noble accomplishment, nod in an impressed manner for a few hours and then begin formulating excuses in your head as to why you never ran no stinkin' 26.2 miles.

Should a friend claim he'd run, biked and swam 140.6 miles (just a little Ironman, people) you might press your eyes wide with shock, smile awkwardly and start peeking in said friend's medicine cabinet for an unfilled psychotropic medication.

But when numbers like 163 start flying around...well, then you run for the hills (er, jog for the hills - you're no crazy person).

But 163 miles is exactly what Will Thomas and Seth Bradbury plan to trek during the upcoming EpicMan adventure. The planned journey launches via kayak from Peaks Island at 2 pm on Sunday, April 19th. From Portland they'll bike overnight all the way to Boston and with the surplus energy the duo will run the Boston Marathon on April 20.

Yup. Full-blown insanity. The lock-up kind.

It's not without purpose, though. The EpicMan represents the birth of the 2009 Zone Urban Epic season.

And it's not without a little merriment mixed in either. Along the 163-mile journey, Will and Seth will be stopping in to celebrate with we sloths in Portland (at Ri-Ra), Portsmouth (Portsmouth Brewery) and after the marathon in Boston (Rattlesnake Bar & Grill, just two blocks beyond the finish line).

Even better, Big Brothers, Big Sisters of Southern Maine benefits from the endeavor. At each pubstop, the folks from Tri-Maine will be on hand pushing raffles and consumption. And as my Tri-Maine "insider" says, "The more party goers the more cashola." The raffles will be based on Will and Seth's arrival time at each stop. And prizes include pairs of Red Sox tickets and cash toward bar tabs.

In preparation, all we spectators and supporters need to do is mark our calendars (that's April 19 & 20).

For Tri-Mainer Will Thomas and self-proclaimed everyman Seth Bradbury, some additional effort is required.

But never fear, folks. These fellows are hot on the training circuit, complete with the stationary gold stallion known as the Sunspirit.

How'd this all come to fruition? The stories are conflicting, but according to Will it had something to do with a gentleman's bet, one-upmanship and a guy in an inappropriately small t-shirt.

Then get yourself out to one (or all) of the stops and show some support (no running involved).
