Multisport trimming

Former Member over 4 years ago

I raced a triathlon yesterday, and coming out of T2, realised that I'd stopped my bike computer, but hadn't properly hit the lap button on my Forerunner to stop the bike leg when I dismounted, basically adding my whole T2 time to my bike data, and losing the first bit of the run trying to make sure the device was in run mode not T2.

I'm a bit of a data nerd and like the data to be accurate. I've gone looking but can't find a way to trim the transition to be accurate to get the correct run and bike data. Is the trim function hidden somewhere for multisport or non existent?

I'm happy to provide the bike and race files if someone is able to adjust it for me too!

You can try it here: https://www.fitfiletools.com/

Though I have zero experience with multisport files, so cannot tell wether it works with it too.

If fitfiletools doesn't work for you, zip the fie and attach it to this thread.

Unfortunately Fit File Tools can't adjust sections of a multisport file. I basically need to move the markers that seperates each section of the race, instead of delete sections.

Cheers, I've attached the zip file. Basically the T2 start needs to be moved to where the bike file ends, and the end of T2/run start actually needs to be where the T2 split starts in the multisport file. I hit the lap button and the T2 started when I actually crossed the line to start the run, so my run should technically be 7 seconds longer. The bike file is more for a time/location reference, I believe the multisport file recorded all the right data, the time stamps for bike-T2 and T2-run just need to be adjusted. tri files.zip

I think I got it. But first before I make any adjustments...

This is tri multisport.fit with 735XT

And Tri bike.fit with Edge 530

Yep the tri bike.fit time and distance is correct.

The T2 time should be approximately 1 min 55 based off the official timing/results.

So the cycling should be about 40:44/16.37 mi, the transition about 1:55/0.23 mi and the run 19:13/3.2 mi?

Adjusting per your specifications, leaves this.

After

Here's the new file - tri multisport-fixed.zip

All this is done using FIT File Repair Tool. Perfect for data nerds, so you might want to look into getting this.

Thanks for that reference I’ll have to have a look.

Just looking at the fixed file (the bottom screenshot) the T2 time shows in the file as 1:22, not 1:55, which makes the run too long. Is that an error?

I was going by elapsed time as the official time. Garmin connect is showing moving time, until you drill down into the details.

I've downloaded that file, and the swim part leg has disappeared completely, and is showing the run starts midway through T2.

Is it possible to set both the moving and elapsed times for T2 as 1:55, and the run to 19:13 and see if that helps fix it?
