The charge 4 has built-in gps. I use it independently of phone and only sync if i want to download the data to the app. Fitbit is owned by google so i was expecting good accuracy.

My only reliable reference for my own fitness is 2.4km timing, so thats why it needs to be accurate.

You want accurate 2.4km , have to run the stadium track, 6 rounds on the inner most lane. I won't use gps to time trial my pace.

How does it looks like on Map?
To check its accuracy, run 1 round in the inner circle of stadium.

Nowadays, a lot of these watch got GPS, Galileo, GLONASS, QZSS and even Beidou.

Accuracy should be high except when it is used in China.

I have been swimming ~ 2 km for about 1 hour almost every night for a few months.

However, while the rest of the body's muscles are toned, it is quite hard to lose that little tummy 😂 I'm cutting down to 2 meals a day recently and the effect on the tummy is more pronounced.

I conclude that for keeping slim, exercise constitutes only 20-30% while food intake is 70-80% of the outcome.

2km per hour may be too relaxed a pace. Swimming is a bit like cycling - you can glide and don't expense much energy between strokes. Try alternating with other exercises. 

 

But tummy bui bak is indeed very hard to get rid. Especially the love handles.

I read many factors, one is the GPS chipset. Recently all new GPS watches uses the Sony chipset, which saves battery life, but compromise on accuracy. That's why alot of Garmin 4th gen  series watch suffers some form of GPS accuracy, also the Polar Vantage V and M.  And apparently firmware code improvement also can improve GPS accuracy, since your position is not precise due to many environment factors, the algorithm in the firmware can improve the accuracy. Like why vehicle travelling on the roads seems to be rather accurate, it's because of the algorithm which snapped your position on the road. So even phone GPS seems to be accurate when using as a car navigator. But running, not so.

Coros Pace 2 seems to overcome this weakness of the sony GPS.

I am still using Suunto Ambit2 which uses early version of Sony GPS chipset.

From Strava map, it looks accurate.

retired my old anyhow buy cheapo reeboks which i used > 2300 km mileage.  soles were pretty worn down and can see some signs of underpronation.

new anyhow buy cheapo pumas (buy because i wanted to run as fast as a puma 🤣) still running in and gave me blisters 🙄 but overall felt less leg fatigue on my regular route due to the better cushioning.  see how long this pair can last 😅

no improvement in pace with new shoes though.  in fact performance probably plateaued and starting to decline liao ... won’t be faster no matter what i do as age catches up.  

不认老都不行

Jin dui. Broke a 5 year old record only to be broken by another runner 2 days later.

Any idea what shoes they wear? For a long held record to be broken in quick succession...I wonder if the footwear plays a part. Kudos to these inspiring athletes nevertheless.

Definitely, the carbon plate shoes are game changers since it was approved.

I'm struggling to have this kind of pace..haha. to do it almost every night is impossible for me.

I thot it's quite respectable....1.5km in 45 mins qualifies you for triathlon, iirc.

Gidey is the latest talent that came out of Ethiopia.

With pace light, it easier (that before) to break WR.

5sec is no easy feat.

We hear more of her name in coming years.

You can try interval training, alternate freestyle fast and breaststroke slow

The commentator mentioned her fatigued face towards the last of her 10km. I thought she looks less fatigued than me just starting out on my first 100m. 😂
