Thanks for visiting the Sun Multisport Events web site. We've created a series of first-class multisport events throughout New England from sprint to half distance triathlons plus youth focused races and running events. We also produce the TRI-MANIA Summit and Expo series, the definitive kick-off to the new season, with events in Boston (3/29/14) and Washington DC (3/22/14).

We are proud to say that on January 27, 2014 we received two prestigious awards in the “Triathlete’s Choice” awards program administered by Triathlon Business International (TBI), an industry organization dedicated to promoting the sport and business of triathlon. Our triathlon series was awarded “Best Race Series” and our Patriot Half was recognized as “Best Small Race” (less than 1,000 athletes) in an online survey of triathletes across the country. If you were among the many who voted for us... THANK YOU! Read the press release here.

TBI Best Series      TBI Best Small Race

We invite you to sign up for one of our races and experience what makes them the best in the region. Our priorities are athlete safety, superior organization, scenic courses, generous volunteer support and careful attention to the little things that add up to an event experience that has exceeded the expectations of thousands of athletes. Come to a race produced by Sun Multisport Events and you'll discover personalized rack positions and teams grouped together in transition, abundant course signage, friendly volunteers, water bottles wrapped in cold towels and ice baths at the finish, finisher medals and more. We also understand the impact our events have on the environment and partner with Athletes for a Fit Planet by taking the Pledge of Sustainability for all of our races (the only MA-based company to do this!).

WHAT ATHLETES HAVE TO SAY ABOUT OUR EVENTS...

It was my great pleasure to race the Cranberry Trifest Sprint. It was as well organized as any major 70.3 or Ironman I've done... well marked, safe, wonderful volunteers... just a tremendous event! Thank you for having me!

My recent experience at the New England Trifest was exceptional; in fact, it was the best organized triathlon that I have ever participated in and that includes the US Nationals.  Your team went above and beyond to deliver an experience for the athletes that I have not seen elsewhere – details like live music, veggie options, vendor mall, professional triathlete presentation, bike mechanics on site, and ice baths at the finish line, complimentary post-race massage, etc (to name a few).  Thanks again for organizing such an outstanding experience - In the infamous words of the Terminator…  “I’ll be back!”

I thought I’d take the time to let you know how impressed I was with how well run the Westborough Sprint Triathlon was yesterday. I’ve been competing in triathlons since 2003 and have raced from sprint distances to Ironman distances. This year I’ve decided to race “quality over quantity” and racing at yesterday’s event proved a quality event. The Athlete’s Guide was very informative, the parking was convenient, the registration check-in and body marking were efficient. The transition check-in volunteers did their job well and the announcements over the p.r. system were extremely helpful. Having teams grouped together in the transition area and having your name and race number on bike racks were icing on the cake!  The volunteers on the course were helpful, the amount of police detail on the course made you feel safe and the finisher’s medal, water bottle and food were excellent! Great sponsors and hip deejay rounded out the race!  You can be sure I’ll be promoting your race next year…not to mention coming back myself to race! GREAT JOB Mark!

Hi Mark, I wanted to let you know that I think you guys did a FANTASTIC job.  The (New England Trifest) race venue was perfect and the organization from the point of registration through race day was excellent.  As always, your volunteers and support staff were also great and so extremely helpful and nice.  I hope you're proud of the event because you definitely should be.

I did your race (Patriot Half) on Saturday with my husband and my father did the Aquabike. I want to thank your organisation for this race. You know, I have done near 150 events in the last 10 years and your race is now in my top 5. We will highly recommend your race for sure. The two loops on the bike and the run were enjoyable, the volunteers were so fine with us, the lunch after race was perfect. Thank you very much to all your team... eight hours driving in the car is not long for this kind of event.

This was my first year doing this event (Cranberry Trifest). I heard from friends who had done it in years past that it was a fun event but you cannot really appreciate that comment until you experience it. I have done many multisport events and single sport events and NO ONE has impressed me the way you put on this event. From the hospitality and helpfulness of the volunteers throughout the race to the shirts that are the absolute best and the cold water bottle and face cloth after the finish (nice touch). The medal was much appreciated too. Such a fun festival family atmosphere for all who attended. Hats off to you and your volunteers. I will be back next year! All the best!

I just wanted to say what an amazing job you did with the Whaling City Triathlon. It was my first tri, so although I don't have anything to compare it to, I thought it was so well organized, everyone was really friendly, the course was incredible, and it was an amazing experience all around! Thanks for all your hard work, it was clear you really put a lot into this. Cheers!

I just wanted to thank you for an exceptional race this weekend. At every turn, from start to finish, this race was well managed. Particular highlights for me were the abundance of volunteers, the great race swag (awesome medals!) and the exceptional organization. This race (Westborough Sprint Triathlon) is without a doubt one of my favorites now and I'll definitely be back next year. Loved the course (particularly the run!). I just wanted to let you know that I think you did a fantastic job and I look forward to participating in more Sun Multisport events in the future. Thanks again!

You never fail to amaze me at the wonderful job you do. I’ve been participating in your events since the first Patriot Half in 2007 and you always come through. Your events are so well organized and packed with amenities such as ice cold washcloths at the finish line.  I loved the cool mist fans and the after race food  was delicious! And what a venue! Beautiful roads to ride and run, perfectly marked, not a chance of going wrong. Thank you!

I feel TRI-MANIA was well run. Seminar/clinic topics were widely varied and content was dead-on and pertinent. Exhibitors were friendly, not pushy. Event staff was helpful, happy, and energetic. Loved the things for kids; most applicable and valuable. Venue and access was good. Overall, excellent! Nice job.

I'm writing you and the entire team of people that made this race possible. It was an awesome 1st time triathlon race experience for me and need to say the event just blew me away... Everything was organized on superb level, all the people were very positive and supportive, the safety of the race and the atmosphere was really great... looking forward to next year's event... keep up the good work.

Thank you for an awesome event last weekend. This was my first Cranberry Trifest Olympic distance tri and just my second Olympic tri overall and I'm not going to lie - the distance was hard -- but the race itself was a blast. Your staff and volunteers were amazingly organized, helpful, and cheerful. The swim in the lake was smooth, the bike loop was scenic, and the run was great even with the hill at the end. All routes were very clear and easy-to-follow with big thanks to the police and volunteers stationed at all turns. I loved the band and BBQ at the finish and also appreciate the race's tech T shirt. I'll wear mine with pride.
