SPIZ is continuing to work great for my ultra-running events. Have gotten several friends here in Marin using it.
Customer
Oh my Gawd! I placed my order for SPIZ yesterday and it was on my doorstep today! Nobody offers that kind of service!
Endurance Athlete
I used SPIZ to help me qualify for the World Duathalon Championships, now I'm taking it to Italy with me next week to race there.

Randy - a HUGE THANK YOU! I NEVER would have made the last 100 miles without the Spiz - I was sucking down 500 calorie bottles for the duration.
Athlete
The SPIZ is great! I used it a few weeks ago on a very hot 80 mile ride that included Palomar Mountain East Grade. I actually felt good when I finished.
Triathlete
I was extremely pleased with the effects of SPIZ on my first IM Triathlon. SPIZ gave me everything I needed to endure the race while not upsetting my stomach.
ProFit Health Solutions
I completed two 50 mile ultras in San Diego late last year and then started my focus back on the Tri Season. Loving the Spiz and highly recommend it to everyone.
Cyclist/Ironman
I liked the SPIZ a lot! I did a 5 hour ride with it the last two Saturdays and it worked great. It will sure make my Ironman race a lot more enjoyable. Thanks again!
Customer
I love your product by the way, having tested many others on the market, I have found SPIZ to be by far the best. Last year I did the Aids/Lifecycle using only SPIZ.
Santa Clara, CA
I really think your product is great. I swear that stuff has something magic in it. When I drink it at mile 150 on a double, I feel like someone gave me a new set of legs.
Athlete
The chocolate SPIZ is incredible it ROCKS! Warm or cold doesn't matter, it goes down, stays down and gets the job done. Got my husband turned onto it also. Thanks for an incredible product.
Ironman Contestant
Hello there! I have previously ordered a number of cases of SPIZ and really believe in the product. My training partner and I used your product and felt it was nothing short of rocket fuel!
Cyclist
SPIZ is great. On long rides I alternate between SPIZ and a light drink mix. Other drink mixes are either too sweet or don't give enough calories to upset my stomach. SPIZ is consistently good for me.
Cyclist
Got back from Italy in one piece, and as usual SPIZ didn't let me down. I finished 7th out of 24 in my age group and 65/400 overall. SPIZ gave me the energy to get through it. SPIZ kept me in the race.
Marathon Runner
In training, I rely only on SPIZ for supplemental nutrition. Being free of gels is hugely liberating for me, and those sugar drinks never worked for me, but the best part is the performance and recovery.
Athlete
I am geared up for the 24 hour race. SPIZ is rocking! Finished a single on Saturday and then a double on Sunday and lost less than a pound of body weight. Normally, I was losing 10 pounds of water weight.
USA
Happy to say that I had a great ride today using spiz, I ride about 100 miles per week. I'm a pretty big guy and have been looking for something that can equal out the huge burn that results from longer rides.
Marathon Runner
I tried SPIZ that you sent me this morning for my marathon. I mixed the chocolate and vanilla with soy milk and it tasted fantastic. It sat well in my stomach and had no stomach issue. I am going to order more.
Athlete
I have been using SPIZ for over a year now and think it is a great product. I has greatly improved my performance on training rides and helped me to finish strong on Century rides instead of bonking at 75 miles.
Customer
Completed my first Texas Water Safari last month and my first use of SPIZ. It was great! Next year I'll be going with more SPIZ and less energy bar type fuel. Got sick of energy bars. Never got tired of the SPIZ.
Customer
Thanks for your help expediting the last SPIZ order. I started using SPIZ this year and have finally found something that works for me. I have done an IM and 1/2 IM this year and for the first time not had any stomach problems.
Alameda, CA
I am an ultrarunner and I just ran my first 100 mile trail attempt at the Headlands Hundred. Using Spitz as a recovery drink just after the effort helped my recover after 48 hours. Really that is more amazing than the run itself.
Washington State
Pending certification by UMCA, looks like my crew and I set the Wa State East-West record this past weekend, 462 miles in 33hr, 38min. Still tallying all the numbers, but looks like a pound and a half of Spiz, plus a bunch of tuna sandwiches.
Nutritionist/Triathlete
With over 500 Calories per serving, SPIZ contains a desirable 5:1 ratio of carbohydrate to protein. SPIZ can be mixed at high concentrations without inhibiting fluid absorption and otherwise triggering muscle cramping and stomach sensitivities.
Jackson, Michigan
I do a lot of bike riding and I've found SPIZ to be very effective at helping me avoid cramps and the dreaded bonking. One of the things I like about it is that it's not too sweet, like some of the other drink mixes, so I use it almost exclusively now.
Cyclist
I have been using SPIZ for about 1 year. I have learned to tailor the concentration to my needs and the length of the race. In this year, I credit SPIZ to helping me win the Mas O Menos 100K Mountain Bike Race and the Sprint Adventure National Championships.
Athlete
Had to let you know the SPIZ is awesome. I've tried it just three times and notice my energy is there at the end. Rode two hours yesterday and got to my finish point and could have easily rode two more! Felt great that evening and recovery today feels good too.
Cyclists
Well, Marcy and I completed our first 100 mile ultra two weeks ago with better-than-expected results. Once again, SPIZ came through for us. I subsisted almost entirely on 1/2 serving of SPIZ every 8-10 miles. Never was lack of energy a problem for me. SPIZ rules!
Athlete
SPIZ mixes with water, that's it. It dissolves easily and tastes like Yoo-Hoo. Seriously! You will not have to choke down SPIZ. No refrigeration is required. It tastes better cool, but if you toss a bottle in your special needs bag, you need not worry about it spoiling in the sun.
Athlete
I tell everyone I train with out with your product. I truly believe it is the best thing out there. My wife and I have been racing Ironman distance triathlons for 5 years now and use SPIZ on all our training days and races. We have never had a problem with "bonking" or GI distress.
USA
I experimented with Spiz in the Wildflower long course triathlon this weekend and first used it in another half-iron distance tri two weeks ago. Wow, best performances ever, with energy to spare. I'm sold on it and have already passed word on about it to others. Thanks for being out there!
Director CaroMont Rehab and Sports Medicine, Gastonia, NC
A patient recently introduced me to your SPIZ energy drink and I was very impressed with the quality, taste and performance. We are often asked about performance supplement recommendations and thought this would be great to promote to our patients and athletes to enhance the rehab process.
Athlete
I just want to let you know that I love your product. Taken me to the finish line on Four Ironman Races and countless 1/2 Ironmans. Last year after a Triathelon Camp, I used one of the "other" products. It couldn't hold a candle to SPIZ. Not even close! I'm sticking with your product for sure.
Customer
I'm an ultra runner and a long time user of your product Spiz. I recently ran the Western States 100 mile Endurance Run for the third time. Spiz was my main source of calories for the entire event. Using Spiz I never had an issue with my stomach shutting down. My finish time of 21:36 was a PR for me.
DPR Construction
I just wanted to drop you a line and let you know the recent success I had with Spiz. I used your product exclusively for 5 days in RAAM with great success. I used Spiz instead of solid food the evening before, the morning of the race before the swim and immediately following the race as recovery. It was perfect.
Beaverton, OR
I compete in Ironman Triathlons and have finally found nutrition that works. On a century ride this past winter a friend suggested I try Spiz. It was incredible! I felt energized the entire ride...what a relief! I just finished IMAZ last week, and while many athletes got sick during the ride and run, I am happy to say I did not.
Marathon Runner
While I know that SPIZ is mostly familiar to bicycle racers and triathletes, I can testify to my success with SPIZ-both in preparation for and during a marathon. More and more over the years I have gradually phased out all use of gels and conventional sports drinks and now concentrate on SPIZ and SPIZ alone. Amazing, excellent product!
Athlete
I just returned from Death Valley where I was on Ed Hensley's support crew. Ed cycled from Badwater to Whitley Portal. During the event, Ed was fueled almost exclusively by SPIZ. During the event, he consumed a whole canister which allowed him to complete the 143 miles trip and extreme climates. I'm convinced, I want to try some! Thanks!

I've been spreading the word about SPIZ over here Down Under. Recently I gave SPIZ another tough workout in the Australian 48 hour track Championships. Again I used SPIZ as a primary source of fuel for the greater part of the event and ended up running a new Australian born 48 hr running record of 244.55 miles, which ranks me 4th in the World for 2008.
Customer
Just finished running my 3rd 50 mile race. In both of the first two events I has stomach issues that cause multiple "system resets". In this race Spiz accounted for more than 90% of my calorie intake. I finished over 1-1/2 hours faster than last year with no issues. I will be ordering more to assist with my 1st attempt at 100 miles at Leadville in 6 weeks.
Ord, NE
Back for more of this wonderful life-giving food. I haven't felt this good, or had this much energy in a very long time! I have gained 5lbs and kept it on this time, which for me is HUGE!!! I no longer look like a skeleton and it's thanks to you and your delicious product. This is the best tasting drink and I look forward to it every time I fix a large glassful!
Austin, Texas
Spiz kept me from boinking big time on a 4 day, 475 mile ride from SF to LA along Hwy 1 (via Big Sur). Total ascent ended up 33,000 ft on my gps so this was not a flat ride. I am very happy with your product, especially not having any "junk" in it. Any stomach load is too much in the heat. It is 100 degrees + here in the summer and I often get 112-115 out on the roads.
Woden, ACT / Principal Toxicologist
I've been spreading the word about SPIZ over here Down Under and have introduced more and more endurance athletes to seeing the benefits of SPIZ. I participated in a 24 hour treadmill race and won the event with a total of 152.84 miles. I could not hold down any solids and did the whole run on Spiz. My energy levels and hydration were awesome throughout the whole event.
Customer
I did Norway's premier long distance bike race last weekend and decided to put Spiz to the test. The race took me 19 hours to complete, and I used Spiz exclusively for the first 15. I was riding happily with Spiz. In the end I was looking forward to each mouthful and relished in the chocolate and vanilla taste. The triathlete community should embrace this wholeheartedly.
US Pro triathlete USA
SPIZ is by far the very best athletic endurance sports drink I have ever used on every level. I can not find a way to make it bother my stomach at any concentration. The most important part of a drink is TASTE. I have higher wattage on my meter, lower heart rate, I have more muscle, lower perceived effort, faster recovery and ZERO CRAMPS. SPIZ is truly the best you can get.
Cyclist
Joe is an avid cyclist... he always had trouble with the longer rides and especially in the longer races. Finally, we convinced Joe to try SPIZ. Huge mistake for me! Once he started using SPIZ he began whipping me in races. He didn't put the whole package together until he discovered SPIZ. I can tell you that it is all I use and have used for the last couple of years is SPIZ.
Regional Sales Manager-Northwest US
I wanted to let you know that I completed my first 100 mile run (the Rio del Lago 100) last weekend, and ran almost the entire race on SPIZ. It absolutely did the trick as I supplemented it with food to take in 350 to 400 cal per hour. I remained lucid and happy throughout the entire 28 hours. My crew told me I was the happiest person they had ever supported, and credited my nutrition as cause. By the way, everyone in my running circle knows I used SPIZ as I couldn't stop talking about how great I think your product is.
