Personal Records - option to select beyond 30-day timeframe

It has now been THREE years since this was first requested. There is simply no logical reason that this obvious and frequently requested feature hasn’t been implemented yet. I am starting to suspect there is a “business” reason… ie: Zwift has a deal with Strava, and the intent here is to “force” Zwift users to also use Strava. If Zwift were free I’d have no cause for complaint, but it’s not free. Rather annoying to be treated this way as a paid user.

It is now three years since it was requested… nothing.

I think the goal of short-term records is to answer the question: is my fitness improving or not? To answer this, I don’t necessarily want to know what I did a year or ten years ago (although these are also useful), but I may be more interested in how I’m responding to recent training.

The time constant for chronic training stress (Allen/Coggan model) is 42 days (default), which implies that fitness depends 63% on the prior 6 weeks of training, 23% on what happened between 6 and 12 weeks ago, 9% on what happened between 12 and 18 weeks ago, and 5% on more than 18 weeks ago. Only 51% is from the preceding 30 days. In other words, fitness changes slowly over time, which is why build periods last months, not weeks.

Given this, I’d think I’d be interested in results over at least the prior 18 weeks (which is responsible for 95% of my present fitness). That’s 4 months, not one month.

Another metric is to consider the number of KOMs in the game. I count 33 “KOM” or “sprint” Zwift Insider Confirmed segments on their list. If I want to make solid efforts at two per ride, I ride 5 times per week, and I want five results to appear on my PR list, then that’s 165 results divided by 10 per week = 16.5 weeks. That would also be close to 4 months.

So I’d put 4 months as a lower bound on how long people are interested in PRs, both from the perspective of how long it takes to build or lose fitness, and on the sheer number of segments in the game for even chronic users.

seems like an ideal addition to the companion app, with route details and past times.

30 day PB’s are now completely obsolete when you can ride 6-7 courses at any given time. It’s very rare that I cover the same ground twice in 30 days, but would want to know my 12 month or all-time record.

This feature together with the personal best bot. So you can ride against your best time and even see it!
Gosh how simple could it be …

+1 from me on this, I’m a two-month new Zwifter and am surprised this feature does not exist. Even if I have been focusing on some specific routes, it’s always interesting to have as much data as possible available (over 30 days). Within a month I might do the same route a handful of times, so why not show more data there? There’s essentially no reason not to, as far as I’m concerned.

An overhaul of this feature combined with the PR bot would make a lot of sense

At 58 I’m not really interested in KOM records from riders more than twice as fast as myself. It would be nice to always see my own PR instead.

3 years since this post started, but I’ll still ask - Please add this feature! I subscribed to Strava premium basically just to see my past times for routes and segments, as well as the details with it, like power, cadence, heart rate, relative effort. Seeing my friends or strangers times is great motivation and fun too. Zwift has all that data, like it shows you on the results screen at the end of a ride. I would love for all my past rides data to be available in Zwift. After getting Strava premium, it’s like my Zwift subscription cost has doubled, just so I can see past times. I think it’s that helpful, or entertaining at least.

very obsolete, often even the 30 day PB isn’t even shown on a group ride,
very obvious on the tedious 3rd climb of the epic KOM where the previous weeks times were not shown.

On several Group rides recently i’ve found that my PB ( in the last 30 days… why can’t this be extended to longer?) for a sprint or KOM is not showing.

The was made very obvious on the recent ToW where my best time for the epic KOM was never shown despite being ridden 3 times in the previous stages.
