Race morning at Jug End State Reservation typically sees a mix of early summer warmth with temperatures ranging from mild to warm, often accompanied by high UV levels and firm yet slightly soft terrain underfoot. The course itself is marked by its hilly nature; runners can expect approximately 2.1 miles of uphill followed by an equal distance downhill per lap around the Jug End Loop Trail that includes both upper loops.
Since its inception in 2016, the Jug End Loop Ultra has become a cornerstone event for endurance athletes and community supporters alike. Over the years, the race has raised significant funds for local causes such as Louison House in North Adams, MA, which supports homeless individuals through various services. Additionally, proceeds from the 4.2 Mile John G Memorial Run are donated to Dana-Farber Cancer Institute.
The course at Jug End State Reservation winds its way through woods and fields with an elevation change of about 830 feet per lap, making it a challenging yet rewarding journey for runners and walkers alike. The start line is set up near the parking area on Guilded Hollow Road where participants will begin their loops around 4:2-mile Jug End Loop Trail at 8 AM sharp.
Weather conditions during August in Egremont tend to be warm with firm trail surfaces that may feel slightly soft underfoot due to recent rains or morning dew. UV index levels can reach high values, indicating the need for proper sun protection and hydration throughout the day.
The race offers a challenging 4.2 Miler covering 6.8 kilometers, priced at $35.00 per registration, as well as an ultra-distance option in the form of a six-hour event where participants run or walk laps around the trail until their time limit is reached for $80.00.
Registration can be completed online via [https://ultrasignup.com/register.aspx?did=132906](https://ultrasignup.com/register.aspx?did=132906), with early bird pricing available before December 1st and discounted rates for those under the age of eighteen using code SUPERKID. Bib pickup will take place on race day near the start area at Jug End State Reservation starting from 7 AM onwards, where participants should bring their confirmation email or a printed copy to receive their bibs.
The start location is situated off Guilded Hollow Road in Egremont, Massachusetts, with age requirements set for all runners. For those participating for the first time, it's important to note that partial laps do not count towards final distances after 6 hours and only complete loops of .75 miles will be scored during the last hour.
