Boulder Reservoir Update

Dear Boulder Reservoir Users and Neighbors,

As you may know, the Parks and Recreation Department is currently planning for the redevelopment of the Reservoir Administration Building and beach area beginning in fall 2018 through spring 2019. We will be investing $3.4 million from the capital improvement budget to to construct a bright and modern visitor services center that enhances functionality and visitor experience.

We will also be issuing a Request for Proposals (RFP) for an associated concessionaire opportunity shortly and are updating construction plans in advance of permitting. For more information about the plans and timeline, please visit the Visitor Services Center Redevelopment page.

We are also excited to share an effort underway by the PLAY Boulder Foundation, the Parks and Recreation Department’s non-profit partner. A Campaign for Boulder Reservoir has launched to support the unfunded amenities at the Reservoir. Through your participation in public meetings and surveys, we understand that the community desires additional features beyond what the existing city budget can afford.

These features include a playground, a boardwalk with overlooks, and more seating and shade. PLAY Boulder is looking to further discuss donor opportunities with individuals who care about the future of this special place in Boulder. For those interested in more information, please feel free to visit or contact PLAY directly at

Thanks for your attention and continued support of the Boulder Reservoir.

The week leading up to a major race, what we call “race week” in the sport, can bring its own breed of stress and anxiety. These emotions can pile up and wreak havoc on an athlete’s race experience and even results. So what’s a high-strung athlete to do? The best chance for success on race week is to do your best to make it as much like any other week in training.

IRONMAN champ Linsey Corbin sums up race week success with this: “Get a lot of sleep early in the week, dial in your race gear early, thank a volunteer, stay hydrated, don’t stress about the weather, do something nice, keep the blood flowing, and have fun.” Below you’ll find a few more handy points to help keep the cortisol levels down.

Tri Boulder Race Recap

The BBSC Tri Boulder race at the Boulder Rez this year was a huge success! Not only was the weather perfect, the water smooth as glass, the temps only moderately hot, and barely any wind, but PRs and a great time was had by almost every athlete I talked to after the race!!

The only complaints I heard were no shade on the run, couldn’t see buoys because we swam straight into the sun, the aid station on the bike was on a downhill so it was hard to gab bottles at high speed, no actual awards for podium finishers, and packet pick up should have been Friday in Denver and then Saturday in Boulder since most people coming into town only came one day in advance.

People loved the finisher’s medal, post-race food, support, volunteers, beginner wave, and low key feel for the race. The thing most people talked about was how fast and fun the bike course was. The roads in Boulder are all pretty fast and smooth. Parking on race morning was easy and there were lots of activities for spectators and families to do during the race.

The courses for both the sprint and the Olympic races are very familiar to most local Colorado triathletes so it’s nice to be able to come in and race hard and compare times and progress to other races on the same or very similar courses.

I had several clients who did the race this year and all either PRd or made the podium. All walked away happy with their result.
This was my 2nd year doing this race and I had a lot of fun racing with so many local triathletes. I was only one minute slower than my goal and I blame it on the sun. It was so bright at the start I swam to the wrong buoy near the turnaround so I added 1-2 minutes on my swim. Other than that I had a great race! I love racing at the Boulder Reservoir and can’t wait to do their next race in Boulder on August 26th, register here and I will see you there!!!

BBSC has triathlons, duathlons, and running races in Boulder, CO, St. George, UT, and Las Vegas, NV. Check out their race schedule here

Tri Boulder Race Preview

By Kirsten McCay

The 5th Annual Tri Boulder Sprint and Olympic Distance Triathlon is coming up and you don’t want to miss this race! This is a perfect tune-up race for the Boulder 70.3 which takes place in the same area 2 weeks later.

Compete in one of the fastest growing triathlons in Boulder. Swim in the beautiful Boulder Rez which is in the mid-70s right now, I swam in it with no wetsuit last weekend and it was perfect! Bike some of the smoothest (yay) and fastest (double yay) roads in Boulder. And run on the scenic dam trail which is a mostly flat and all packed dirt road. BBSC is a tri-friendly, professional race company that offers gender specific t-shirts, finisher medals, age group awards, Clydesdale and Athena categories, relays, race day child care, free entry into the reservoir, post-race food, and more.

This year I am doing the Olympic distance race and have already spent time on both courses and wanted to share with you what you are in for when you decide to do either of the races this year on July 23rd. I’m using the Olympic as a training race for USAT Age Group Nationals on August 12th. Either distance would be great for that or as mentioned above a tune-up race for Boulder 70.3 on August 6th.

SWIM: Currently the water in the reservoir is about 74 degrees. This is a great temperature that is warm enough for you to swim without a wetsuit if you don’t have one, but isn’t too warm to legally allow wetsuits if you are relying on that to help your swim time. The sprint course is a 750 meter clock-wise rectangle and the Olympic just doubles the distance out and back from the shore. There will be large buoys at each turn and small buoys for sighting. The swim is a wave start for safety and ease for beginner swimmers. Typically there are less than 100 people per wave.

BIKE: The bike course for the sprint is typically called the “Neva loop” and is basically a large loop around the NW part of Boulder. The sprint course is 17 miles, a little longer than the usual sprint distance, so if you are a cyclist, this race is for you! After leaving Reservoir Road, there is a very gradual climb for about 3 miles and then a fast rolling downhill for the next 10 miles. Once you are back on the Diagonal, it is another very slight incline for about 2 miles and then basically downhill (other than 2 short hills on the road back to the res) to the finish. The Olympic starts and ends the same way with a couple extra miles of slight incline rewarding us with several additional miles of declines! YAHOO!

RUN: The run for the sprint is primarily on dirt road and is a simple out and back around the res along the dam. There is a hill immediately when you leave transition, just remember it will be downhill on the way back when you need it the most. The Olympic is also an out and back, it just passes the sprint turn-around and goes an additional 1.55 miles slightly inclining to the 10K turn-around which will be fast for the return home to the finish line.

A great way to practice the swim and run is the Boulder Stroke & Stride which is a swim/run series held at the res every Thursday night. This will get you used to open water swimming, running up the beach, and that first hill on the run.

If you get to the Stroke & Stride, stop by and say “HI” to me at the “chip handout” table!!

And I hope to see you all out there on the 23rd.

Tri Coach Tuesday: How Cold is Too Cold?

Living in Colorado, we’ve come to learn that spring weather is unpredictable at best.  This can make for less than optimal conditions for swimming and racing outdoors.  Many of us have been disappointed when our anticipated triathlon becomes a duathlon or an OWS gets postponed or cancelled all together.  Although it doesn’t always satisfy our disappointment, the race directors always have athlete safety and well being in mind when these decisions need to be made.


Some venues have strict guidelines they follow.  Often times it comes down to a combination of swim distance, water temp, air temp, wind speed, type of event, etc etc.  In the end, if an event goes on as planned, the decision to participate comes down to the athlete.  Some athletes  can handle 52 degree for 1/2 mile, while others should opt out at 57 degrees.


Without Limits Productions RD, Lance Panigutti, reminds everyone that “RD’s have to make a determination based on all the athletes safety and skill set.  While some elites may be able to handle more extreme circumstances everyone needs to understand that it’s about the collective whole when it comes to moving forward to cancelling/modifying a portion of the event.”  He adds, “Every athlete needs to know and practice what they can handle, prepare for everything and hope for sunny skies”.

Bottom line:  Be educated on the effects of the cold and how they effect you.  In the end, you are responsible for your safety and well being in any type of event.


Other things to considered:


Cold Shock

Cold water zaps your body heat 25 times quicker than cold air. Add to that the physically exhausting nature of swimming, and you’re losing body heat at a rapid pace. Extremely cold water — 50 degrees or below — can lead to cold shock. This occurs when the body is overwhelmed by extreme cold, and it can send your body into a heart attack or unconsciousness, the latter of which can lead to drowning. Your body responds to a sudden plunge into cold water by making you involuntarily gasp, and if you’re under water this can cause you to drown before you get to the surface.


You’re probably well aware of hypothermia, which occurs when the body loses heat at a rapid pace. This can also occur in cold temperatures of 50 or below. While hypothermia takes longer than cold shock, it can be just as serious. Exposure to cold water for long periods of time lower your core body temperature. The lower it gets, the less your body can function. Once your core temperature reaches 93 degrees, you’ll be unable to use your arms and legs, and your mental function begins to deteriorate. At 80 degrees, you can become unconscious and drown.


Excerpt from


Excerpt from

One can’t reasonably expect to go from pool swimming to doing an hour in 7C / 45 F without a wetsuit, based on desire to swim alone. Granted, this isn’t likely to occur, but I’m trying to illustrate a point.  Ability to handle COLD is again a matter of a few factors more important than others (all other things like alcohol, food, illness, sleep being equal): namely, experience and weight.

People with plenty of experience of cold can swim in very cold water. I can swim for 20 minutes in 5 C / 40 F water, because I’ve gotten used to it. But I certainly don’t recommend it and I won’t claim it’s fun. And the bigger and heavier you are the more you can handle with less training. Fat is an insulator. Just having plenty of fat alone makes cold easier to deal with. But fat does not lessen the pain of the initial shock for example.

I have done some reading on regular cold water immersion. It seems the evidence says regular immersion in water temperatures of less than 10 Celsius is very beneficial for health, in a few different areas; improved respiration and circulation, lessened chances of infection and heart attack. However once the time goes over 10 minutes some of those benefits tend to reverse, especially hypertension and cardiac arrhythmia.
