The Trek Across Maine, a three-day, 180-mile fundraising cycling event, departs Sunday River Ski Resort in Newry Friday, June 15, and arrives at Steamboat Landing in Belfast Sunday afternoon, June 17.

As the largest fundraising event of its kind in the nation for the American Lung Association, the Trek has raised more than $24 million in the past 30+ years.

Motorists take note: Signs will be posted and traffic diverted from the Trek route into and through Belfast to the landing, as has been done in years past, and traffic will be halted at intersections to allow bikers to pass through.

The Trek Across Maine offers three route options for one, two or three days of cycling.

The full three-day trek is 180 miles with two options. The standard route is Day 1, June 15, Sunday River to University of Maine at Farmington (approximately 67 miles) with three rest stops; Day 2, UMF to Colby College (approximately 57 miles) with three rest stops and one water stop; and Day 3, Colby College to Belfast (approximately 56 miles), with three rest stops and a last mile staging stop.

The three-day Colby Loop route is Day 1, Sunday River to UMF, shuttled to Colby College to sleep (approximately 67 miles); Day 2, Colby Loop Route around Waterville area (approximately 41 miles); and Day 3, Colby College to Belfast (approximately 56 miles).

A two-day, 102-mile option begins Saturday, June 16, at Colby College and ends at Steamboat Landing.

New this year, a one-day, 56-mile option June 17 also starts at Colby and ends at Steamboat Landing.

The Trek's fundraising goal is $1,477,000; the latest tally posted on its website is $901,260.79. Among the teams participating, a local group from athenahealth in Belfast to date is ranked second, having raised $54,816.

Athenahealth employee Billy Yanniello decided that for this year’s Trek Across he wanted to challenge himself and his donors. If he could raise his fundraising goal of $1,100 for the American Lung Association, he would not only bike the three-day, 180 mike Trek, he would bike from Belfast to the start of the Trek instead of driving or riding a bus with his athenahealth teammates.

In April he hit that fundraising goal, so he is adding an extra day to his Trek bike ride and an extra 120 miles, starting at athenahealth.
