With the Charles River, HarborWalk, Boston Marathon course, and famous sites clustered along the 2.5-mile Freedom Trail, Boston offers runners plenty of options. And routes that stretch three to six miles can encompass a surprising amount of historical ground.

RunBoston (www.runboston.org) gives customized tours for individuals and couples with hotel pickup. Customers choose when and where they want to go and how fast they want to run.

Prices for personalized tours range from $50 to $70 depending on the distance, with discounts offered for additional runners. The last nine miles of the Boston Marathon is one of RunBoston’s most popular tours, a close third behind runs along the Freedom Trail and Charles River.

Freedom Trail Run (www.freedomtrailrun.com) takes large groups on a 5K course that covers, yes, the Freedom Trail. The $40 tours start at the corner of Park and Tremont streets and finish at the Charlestown Navy Yard with a ferry ride to Long Wharf. Private group tours are available for $20 to $40 per person.

City Running Tours (www.cityrunningtours.com) draws crowds with its 10K Boston Seaport Beer Run that starts at Fish Pier and finishes with a tour of the Harpoon Brewery. The company, which has outposts in large cities across the country from Philadelphia to Minneapolis-St. Paul to Seattle, also offers a 10K run through the North End and 5K runs through Beacon Hill-Back Bay and Cambridge-MIT.

Running tours tend to be particularly popular with women, who face more safety concerns when running in an unfamiliar city.

The 10K Boston Seaport Beer Run traverses an impressive amount of territory, about 6.8 miles, in 90 minutes. The tour gives runners a look at old and new Boston, heading down Seaport Boulevard to the Rose Kennedy Greenway to Post Office Square to the Boston Common to the Freedom Trail. The route winds its way to the TD Garden for pictures with the Bobby Orr statue and to the North End, coming to a scenic crescendo as runners jump on and off the HarborWalk on the way back to the Seaport District.

The Beer Run is led by Brian McCarthy, manager for City Running Tours in Boston and a marathoner. “I love sharing the city with people,” McCarthy said. “Half of my clients are local and they have never seen the city this way. They didn’t know where Paul Revere was buried or about the Custom House. I’m a history buff and I’ve turned a lot of my guides into history buffs, too. Plus, a lot of them have their own things to offer, especially the ones that live in the city.”

Prices range from $25 for 5K runs to $45 for 10K Beer Runs. Additionally, you can arrange personalized runs that cost $75 for up to 6 miles, with $5 each additional mile.
