While all reasonable efforts are undertaken to ensure that the charts reflect a correct interpretation of the information, the owners and authors of this site make no guarantee whatsoever in regard to the accuracy of the displayed images and data.

Data Quality
The charts are dependent upon the accuracy of the underlying data. Before calculating the images we examine the quality of the data and where necessary make reasonable judgements about any absent or obviously incorrect information. Many numbers presented in this analysis are interpolated or extrapolated from the limited information captured during the event. Standard mathematical procedures are used in our calculations, and all displayed information can be logically traced back to the source data.

In most implementations of Runpix your division is represented by a letter and a number. The letter is your gender and the number is the 10-year age grouping into which you fall. Hence M3039 represents Males 30-39 years of age.

Net and Gun Times
Net place and gun place are independent. Consider a 2-person race: The gun goes off, you halt to tie your shoe lace and then start with a 20 second delay. You run to the finish and the other guy is nowhere in sight. You have come in first place. Your net is faster than your gun by 20 seconds. The other guy has a major delay at the start and gets under way 2 hours after the gun shot. But he runs very fast. Of course he finishes in second place, but he wins on the net time - because he covered the distance from the start line to the finish line faster than you covered that same distance. The result is your net place is 2nd and your gun place is 1st.


Placement charts
The 3 placement charts which demonstrate your finish position are crafted so that the location of the pointer along the base line is proportional to your finishing place. In some circumstances, these charts may reflect very small numbers of entrants. For instance, your category may have only 1 or 2 people in it. In such circumstances, the location of the overlay figure might be open to discussion - where is the appropriate location for the overlay for the 2nd person in a 2 person race?

Speed and Split times
The split times indicated are your average for the entire event. Unlike your finish order, a split time is a personal result which is independent of the results of others in the event. For this reason, it is appropriate to calculate split times from data captured from personal timimg chips. Where this chip data is available - and reasonable - we have used it for split results. Where this is not the case, we use the clock time. Average speed values are calculated similarly.

Bird's Eye View of finish line
This view is particularly interesting to entrants who choose to finish near an aquaintance. You are able to see the time-location of your friend when you crossed. Depending upon your browser, you may be able to see information about co-finishers by resting the mouse pointer over the colored dots.
The Bird's-eye view has limited accuracy in terms of the positions of the dots. The view is actually based on time (rather than distance), and is accurate only in the way the green dot (you) relates to all the other red/yellow/blue dots in terms of time. This means that each red/yellow/blue dot is precisely placed in relation to you (green) in terms of seconds. However if you consider the location a single red/yellow/blue dot compared to another red/yellow/blue dot, the position shown represents only an approximation. This chart is based on actual time of finishing.

Comparison to Race Photos
In most instances the accuracy of the Bird's Eye View graphic can be confirmed against official race photos. Some variation can occur where another distance uses the same finish line at the same time. For example a half marathon runner may appear in the photo of the marathon finish, but will not appear in the RunPix Bird's Eye View graphic.

Location on course
Your location on the course when others finished is calculated from a comparison of your time against the leaders' times. Where usable chip timing is available, we incorporate chip data into our calculations. Additionally, if usable intermediate chip timing splits are available (for instance 10k, 21.1k, 30k) we include this data in the analysis. Chip time calculations take account of the time you spent behind the start line at the beginning, and also permit us to factor in your varying speeds along the journey.

Comparison with other results
In some situations, users may notice slight differences between RunPix results and those published elsewhere on the net. Variations may arise from factors such as the methods used to handle missing information. A record may show no gender or no category for example. Definitions can also contribute to differences in data. For example, the finish order graphics could be calculated on the basis of your place in the field of starters or alternatively the field of finishers. Other differences may occur when identical times are recorded for 2 or more runners and different criteria used in establishing their placings.

Map Accuracy
Generally speaking, when no intermediate mats are used, you can apply the following rule-of-thumb to more accurately find your map location: If you believe you ran faster in the first half (than the second), you can visualize your location as slightly forward of the marker. If the opposite is probably true, move the marker back a little.

Count of Runners You Passed
This count is derived from Bib numbers ahead and behind you at the two locations. Accordingly a runner who passed you, but was subsequently passed by you, will not be included. This count is dependent upon the accuracy of all runner's
