More background work.

• Fixed bugs old and new.
• More refactoring and improvements to the code base to allow for new developments.
• Soem minor visual improvements across the stats.

Lots of things under the hood this week.

• Updated Distribution charts so tooltips show percentage and cumulative percentage for each bar of the histogram E.g. Ironman Wales 2025 Finisher Distributions.
• Refactored a lot of code in ways that will be useful in the future but make no visible difference to the site.
• Now handle invalid race and series IDs gracefully.

Many changes to Age Group stats pages and corrections to other qualification stats issues.

• Updated Age Group summary pages to show qualification ranking times and better support the new qualification system. E.g. M50-54 Age Group Summary.
• Updated age group stats pages to load data separately and improve page load times. E.g. F30-34 Top 20 Splits.
• Major improvements to how 70.3 qualification ranking is handled - displaying ranking within genders for 70.3 results. E.g. 2025 Results for Ironman 70.3 Knokke-Heist.
• An embarrassing number of bug fixes relating to the slot allocation changes and other issues.
• Various changes to backend code to allow for greater flexibility in the future.

Lots of minor changes and fixes this week.

• Numerous bug fixes throughout the backend and general improvements to code.

• Implemented a 'Donate' button across the stats section to help support maintenance and development. If you'd like to help, why not make a donation?
• Created the 'Can I Qualify?' page to check goal times against qualification rankings at recent races. Can I qualify?
• Added the 'Rank Me' page to each race, check how specific race times would rank over past years of racing at that event. E. g. Ironman Vitoria-Gasteiz Rank Me page
• Updated the navigation elements across the stats section for (hopefully) improved navigation.
• Numerous bug fixes throughout the backend and general improvements to code.

After weeks of minimal updates, it's a big one!

• Uploaded missing Ironman 70.3 data from 2024 through to July 2025. Find them on the Recent races page.

Much needed bug fixing for Ironman 70.3 data.

Another small update without major features. Been working on some other stats.

• Implemented a share button across the site. Find it on many pages and posts, including this one. Feel free to share the content.

• Various visual changes to the site to make colouring more consistent and hopefully cleaner.
• As always fixed other things I spotted along the way.

• Getting ready for changes to qualification in 2026 I updated the qualification pages to given the option of assigning slots by gender or for everyone. E.g. Ironman Australia 2025 qualification.
