New England waterways were one of the best things about the region, attracting colonists with ample water to drink, water for power and water for transportation. The first colonies chose locations on the coast for commerce and travel but were mindful to ensure access to pure drinking water. Their original choices reflected their modest size. Often a clear spring or brook would be the chosen center of a new community. Water in New England before colonization New England was blessed with features that provided much help to development of early water supplies. For one thing, there were abundant natural ponds and lakes. For another thing, there was enough elevation change and transmissive soil to provide good recharge to rivers and to create springs and artesian groundwater flow.

  • Where We Train
    where we train Fresh Pond Fresh Pond is a beautiful 2.5-mile dirt path loop around the Fresh Pond Reservoir. The loop has a large concrete path with a small dirt path to its side. The run to and around is very flat. This run offers a great mix of road and dirt trail run- ning, as the beginning part of this run is a mix of road and river trail. Fresh Pond is about 3.5 mlies from the Track & Tennis Center and a nine mile total when only running one loop. Brookline Reservoir A quick 2.5 miles of road running from the Track & Tennis Center is the Brookline Reservoir. This reservoir is 1500m around and the perfect place for cross country workouts. The path around this reservoir is made of a soft dirt that is very flat. Down the street is Fischer Hill, which is a fairly steep and slightly windy quiet road that is perfect for hill repeats. Chestnut Hill Reservoir Only a mile away from the Brookline Reservoir and about 2.5 hilly miles from the Track & Tennis Center is the Chestnut Hill Reservoir, or as we like to call it given its distance from Boston College, the BC Res. This reservoir is a 1.55-mile loop similar to the Brookline Reservoir. This dirt path is great for tempos and long repeats. Heading from this res to Brookline or vise versa is a classic team run we call “Res to Res.” where we train Heartbreak Hill Known for its place in the Boston Marathon, just four miles away from the Track & Tennis Center you’ll find Boston’s most famous hill.
