Boston Buildup Winter Series

A series of four progressively longer races. Now in its 47th year, this edition will include modifications to accommodate pandemic restrictions and guidelines.

You may register for any of the four individual events or for the full four-race Series. The first 125 Series registrants will receive custom Buildup socks, to be distributed prior to or at the first race.

Please note that while we hope to be able to conduct all the  races of the Series as in-person events, the ability to do so is based on permission from the state and towns. While we will make every effort to hold the races in person, including changing the location, the fluctuating nature of the COVID virus makes it possible that some of the races will need to be held as Virtual events. Please read our Refund Policy before registering.

FACILITIES: Buildings should be open at all races. Come dressed to run, bring warm clothing for afterwards. Mile & 5km splits marked (every km in 10K). Digital clock at finish. ChronoTrack B-Tag timing (gun times, net times where possible.).

POSTPONEMENTS: Postponed races will be held the following Sunday at the originally scheduled site and time. Postponement notice will be posted on this site and the Buildup Facebook page and Twitter feed by 7 a.m. race day (or earlier when possible), and via email to all entrants and those on the Club Connecticut race information maillist.

AWARDS: Long sleeve technical 1/4 zips to the top Overall, Open (39 & under), Vet (40-49), Master (50-59) and Grandmaster (60 & over) male and female in each race who have not already won. The overall Series winners in these categories will receive custom engraved slate plaques after the Series conclusion. Grand Prix Series scoring will be based on the Purdy computer point tables, and weighted (best race multiplied by a factor of four, second best by three, third best by two, worst unweighted). Series standings will be posted at this site after 2 races. Jeff Falberg, Series Statistician.
