Time in Hand Calculator for Randonneurs, v4
· v4.1.0
About
These data fields calculate your 'Time in the Bank' or 'Time in Hand' during your brevet or permanent.
This calculator includes tables for the following closing times:
- ACP 90 Hour rules. This calculator calculates control close times based upon the ACP 90 hour rules, as interpreted by RUSA. It's applicable to all ACP sanctioned events run RUSA.
- RUSA Permanents. Similar to 90 hour ACP rules, but without the 'bonus minutes' that riders get on 200k and 400k events. Supports RUSA rules for very long permanents ( 200k/day )
- PBP 80, 84, and 90 Hour Rules for 2023.
- Uniform 90-Hour time, as used by SIR.
- R80/R70/R60 rules for over-achievers.
The PBP calculators are based upon the timetables published by ACP, and require no special adjustments.
You can find instructions on loading the app on the Garmin Site. You can select the desired time rules from the Garmin Connect app on your phone or from Garmin connect on your computer.
More detail about the app and how it works is available at the link for the source code on the app page.
Warning!!! On a long ride such as PBP, there will be some error with regards to actual ride length. The calculator gives you an estimate of time in hand, and this estimate will drift off as the ride goes on and your individual ride diverges from the official route. The calculator can't tell distance on route from distance off route - detours will give you un-earned time in hand.
The 2023 PBP route as published by ACP is either 1219 or 1224km, depending on what files you look at. Thats about a 20 minute difference.
When in doubt, check your brevet card. Doubly so if you're going for Société Adrian Hands
