2 years ago occassionally go there one, a few times with my kid too at 6am. Then stop by at Ghim moh hawker for BF.
If run at night, need to have rear red LED clip on. Front can just be your mobile phone in the hands or something, coz you'd need some bare illumination for the path anyway. Any $5 cheapie would do, since it's literally pitch black.
Rare occasions would have foldie or bangla on bike gunning through. Once I was already doing like 22kmh and a bangla still overtook gunned past me....... haha. @$#$@@#% Another time was a hybrid bike or road bike, not sure, but it was the big wheels 650/700cc bike.

(ok, 22kmh already past the limit i know)
These fellas do use RC as transporation.
The bikes would try not to use any good front illum (coz would blind oncoming dir), and some runners wear dark clothings. So cyclists would typically only get like 1-2 seconds max of warning time at best, cant find the exact night cycling vid but the runners just suddenly pop out of the darkness one, so quite dangerous.
If wear pure black, i think literally just 1 second of visibility to the cyclist.
For ref :
Yeah 120g, just for info and reference nia....i came across that interesting vid 2 weeks ago that Holly Archer so magnanimously shared on youtube, and with decent scientific rigour too with the whole process documented.
In case there are any hardcore folks here who are so into milking out the last bit of performance to go for sub -3 and wants to heat train lah......max out fueling etc.
I not pro and chasing long races/race times that need such fueling, only amateur sessions with no time limit with kid that need fueling coz burning heckloads of calories.
But i shared with xllms maltodextrin powder on iherb.......and it's really cheap. Like 1/3rd the price of gels.
Wondering if DIY small packets of maltodextrin powder mixed into the cups of water (ie liquid nutrition) works too for your race day or not. It just MIGHT be better than gels, which quite most times you'd want to swallow with water as well anyway. Can try if interested.
