Race Date and Time(back to TOC)The Boston Light Swim, a local tradition since 1908, and the oldest marathon swim race in America, starts at the Harbor Lighthouse on Little Brewster Island, continues on past Georges Island and Rainsford Island, passes under the Long Island Bridge, winds around Thompson Island, and finishes at the L Street Bathhouse in South Boston.
Race-day check-in for swimmers and media is 90 minutes before the start at the Boston Harbor Yacht Club, 1805 Columbia Road, South Boston (between Castle Island and L Street Bath House). Boats will depart from BHYC 1 hour before the start and proceed to a position abeam of Little Brewster for the start. Reporters and photographers wishing to accompany the race armada to cover the event need to contact John Werner, race coordinator. Swimmers and race officials are also available for interviews with the media at the pre-race dinner at 7:00 p.m. the evening before the race at the Boston Harbor Yacht Club, which is just down the street from the Yacht Club.
Course (back to TOC)Based on last year's performance, starting about 5.5 hours before high tide gives swimmers sufficient time to reach the inner harbor well before high tide, so they still have a slight current assist at the end. The potential difficulty with this start time was insufficient current in the outer harbor (Boston Light to Long Island Bridge). However, the current was fine last year, and times were much better than when the race started 3 hours before high tide.
The other desire is to start early in the morning to minimize the waves generated by boat traffic. According to the chart below, the best date is Saturday, 6 August. Saturday, 20 Aug or Sunday, 21 Aug is also possible, but Saturday is a little better then Sunday but 06:45 is a bit early. The 07:30 start is a bit early, but is better than starting late. Pushing later runs the risk of encountering outgoing current in the inner harbor. The conclusion is a start at 07:30 on 6 August 2005.

The Boston Light Swim is an annual 8-mile swim in Boston harbor. The swim starts at the Boston Harbor Light on Little Brewster Island and finishes at the L Street Bathhouse in South Boston. The swim takes 3 to 6 hours, depending on the swimmer's speed and race conditions. The water temperature will be between 58o and 65o F at the start and will rise closer to shore. This year's start will be 5.5 hours before high tide, so the current will be with the swimmers, especially in the outer part of harbor up to the Long Island Bridge. Each swimmer or relay team needs an escort boat. Boats and swimmers meet at the Yacht Club and travel to the starting area. Following a 5-minute warning horn, the race will start with 2 horn blasts at the appointed time. The course is south of George's Island, north of Rainsford Island, south of Long Island under the bridge, north of Thompson Island, and finish at L Street Bathhouse. A high-resolution map is available.Weather (back to TOC)

Race-Day
Events(back to TOC)
The race starts at 7:30 am on 6 Aug 05 at the Boston Light House. Since it takes at least 30-45 minutes to reach the Light by boat from the South Boston, escort boats should leave the Yacht Club by 6:00 am. Park on Columbia Road or side streets, preferably toward the finish line, which is about 4 blocks west at L Street. The race will start with two blasts on an air horn. There is a single blast 5 minutes before the start. Escort boats should know the course. Please make sure you have the course in mind on the way out as you pass landmarks. The waves in the outer harbor can be significant depending on the wind. Easing into a swimming rhythm gradually at the start may be necessary. In 2001, some swimmers were forced to start with breaststroke. In 2002 and 2003, waves were slightly smaller. The current will be strong (~1 mph) in the first half of the race---and in the right direction! Pass south of Georges Island (2 miles), then north of Rainsford Island (3.3 miles) heading for the southern tip of Long Island at the bridge (4.6 miles). Because of the current, the time to the bridge can be as fast as 1.5 hours, but water conditions may alter this time. Beyond the bridge, currents will be across the swimming direction to Thompson Island (6 miles). From the bridge on into L Street the water can be choppy, but starting early in the day may limit the effects of boat traffic. Starting more than 5 hours before high tide will give a slight current assist at the end of the race.Awards (back to TOC)During the race, heading for the proper side of the next island is the best navigation method. Finding the finish line can be difficult. The bright handball courts are often visible. There's a large FINISH banner on the beach. Aligning to the left of the Hancock and Prudential buildings is also possible. There's a fairly tall building behind the squash courts and the land falls off abruptly on the horizon. Remember to look backwards as you motor out to align landmarks.
The first-place male and female swimmers will receive really nice glass awards - 14 inches tall - diamond shaped. The next 5 finishers will receive glass awards. The top 25 swimmers will receive medals. Each competitor will receive a Boston Light Swim T-shirt.Swimmers (back to TOC)
The swim consistently attracts a diverse talent pool. Last year's competitor list is one of the strongest in years. More information on swimmers will be available later. See information from previous years.

Final Check List (back to TOC)
Start time Based on experience in 2002 and after, the start will be about 5.5 hours before high tide to keep the current with the swimmers throughout the race. In 2001, the race started 3 hours before high tide, and swimmers got caught swimming against the outgoing tide. Start The start is marked by 2 blasts on an air horn. At five minutes before the start, there will be 1 horn blast. Swimmers usually enter the water at the start, not before. Boats congregate near each other off Little Brewster Island, but there's no particular starting line. Race Attire Swimmers are allowed to wear swimsuit, goggles, and cap only. Wearing a wet suit disqualifies you from placing. Vaseline is allowed, but not many swimmers use a large amount. As chaffing can be a problem, some swimmers put Vaseline under their armpits. Sunblock Sunburn is a potential problem. Starting early in the day will help this. Using sunblock may help. Eating and drinking There are different strategies for eating before and during the race. Stopping frequently can waste time, but eating and/or drinking, say every 1-2 hours, is important to give energy to your muscles. The sugar you ingest starts working in 30-45 minutes, so eating an hour before the race might help. High-energy fruit drinks are popular. Some people recommend warm drinks to alleviate the cold. Ask your fellow swimmers. Because getting food from your boat can be difficult in wavy conditions, carrying Gu or other performance gels in their packets INSIDE YOUR SWIMMING SUIT is a good way to have energy handy.
Choppy water Boat traffic and wind can produce significant waves. The best strategy is not to fight them. At the 2001 start, waves were a problem; conditions for 2002 were milder. Before the bridge, the waves are likely to be with you. After the bridge, waves can be diagonal to your path. Coping with the waves is part of the race (fun). Chafing Irritation of armpits, shoulders, or neck can be significant. Strategies include don't worry, use Vaseline, or place bandaids at irritation points. Navigation Don't underestimate the need to choose a straight path. Before the bridge, heading for the proper side of the next island works well. Larger boats have to be careful of shoals. Passing under the bridge closest to Long Island is best. Depending the current, heading toward or east of Thompson Island might be ok. After Thompson Island, you need to find a landmark, like the bright handball courts, to point to. Skirting the anchored boats off shore before L Street is necessary. Look for the large Finish banner. Relieving yourself It may be necessary. Swimming and peeing at the same time is close to impossible (for guys at least). We may need to gather more information here. Escort boat position Your boat has to stay with you, either to the side or in front. You should work out a strategy with your boat captain. Dropping out If you quit, make sure you get word via cell phone to the race coordinator or by coming to the finish line to tell somebody. The cutoff to rach the finish line is 6 hours. If a swimmer hasn't finished by six hours after the start, he or she must motor into shore.
The Finish Get to shore. A little butterfly at the end wows the crowd. Find the finish judge. Get some food. Bask in the glory of completing 8 miles in Boston Harbor. Tell your friends. Cheer on other finishers.
