 Can I use the Multiple event Discount with a Team Discount?

Unfortunately, you have to use one or the other. However, this discount is greater than the team discount.


BuDu Racing, LLC works with participants who have a legitimate refund requests. For this series pass, it becomes more problematic, so it will be handled on a case by case basis. Passes can not be transferred to other participants. Please email Info@BuDuRacing.com if you need to request a refund.

 What is the BuDu Championship?

At the request of a number of BuDu participants, we are creating a Championship Series. It will recognize the top age graded winner of the series, for both male and female and Olympic and Sprint distance.

 How is the Championship Scored?

This means that, a ranking number for the event will be multiplied by the overall time for the participant, giving a score for the participant. So, just because you are the fastest finisher, you may not be the top Age Group Ranked Finisher for the Championship! This age grade ranking is only for the CHAMPIONSHIP. The following is the criteria for scoring:

For Sprint (Short Course):

  1. Participate in at least 3 Sprint events
    2 BuDu Racing, llc events and 1 other event that BuDu is the hired timer for (see above)
  2. Average of best 3 Sprint events
  3. Winners scored by Gender
  4. Top 3 are BuDu Champions!

For Olympic (Long Course):

  1. Participate in at least 3 Olympic events
    2 BuDu Racing, llc events and 1 other event that BuDu is the hired timer for (see above)
  2. Average of best 3 Olympic events
  3. Winners scored by Gender
  4. Top 3 are BuDu Champions!

 What is Age-Graded Percentages/Times?

Age-Graded Percentages and Times are adjusted so that they may be compared for all ages and genders.  Times are adjusted to reflect what one could theoretically achieve at their prime (early 20s) and percentages are calculated so that performances can be compared across both age and gender.

 How are the adjustments to the percentages calculated?

Previous years USA Triathlon (as appropriate) rankings at the 5th percentile for each age group is use to as a basis for age-graded calculations. Therefore, a male age 35 at the 5th percentile would have a similar percentage as a female age 50.  Similarly, athletes performing at other percentiles should have similar percentages across age groups.  Since most age groups have over 1,000 athletes ranked, there is enough data for reasonable accuracy.  However, in older(70+) and younger(15-) age groups there are fewer athletes ranked, so in some cases the 5th percentile ranking was adjusted.

 How can you compare different triathlon events when the courses and conditions are all different?

Unlike age-grading certified running road races the triathlon courses can be unpredictable.  Therefore, to compare different races, USAT rankings are again used.  Each race is ranked according to competitors previous rankings compared to their race day performance.  The rankings for the event are used to calculate the adjusted time and percent.  Using this method, different races can be compared with a percentage variance usually within 3%.

 I had a faster time than someone in my age group, but he had a higher percentage than me. How come?

He was probably older than you.  The age adjusted percents are based on age, not age group.  For a group such as 35-39 there is not much variance, but in an older age group(65+), the older athlete will have more of an upward percentage adjustment.

 How do I interpret the percentages?

Using the track and field Class nomenclature, the following may be used as a guideline:

  • Over 95% – World Class
  • Over 85% – National Class(near the 10th percentile of USAT rankings)
  • Over 75% – Regional Class
  • Over 65% – Local Class
