Tokai University Installs 325-LED Electronic Pacing Light System at Home Track



On Apr. 14 the Tokai University track and field team and Faculty of Engineering announced that in March they had installed an electronic pacing system at the university's home track at its Shonan campus. The pacing system involved LED lights placed around the edge of the track, which light up sequentially based on the set pace. It is the first time in Japan that this kind of system developed by a domestic manufacturer has been permanently installed at a track.

LED pacing systems are used internationally at Diamond League meets and high-level time trial races. Domestically they have been introduced at events like the National Championships 10000 m, Hokuren Distance Challenge and Hachioji Long Distance meets. They have become popular with fans for adding color to the visual presentation of the race and for making it easier to follow the pace of the race.

Tokai University began plans to develop and permanently install an electronic pacing system two years ago. The system was developed in collaboration with Takamizawa Cybernetics, a company headed by a Tokai graduate that develops, manufactures and markets social infrastructure-related electronic equipment. The system it made for the Tokai track features 325 LEDs positioned alongside the inside of the track. The LEDs can flash four different colors, including red and green.

The system is set to be used for the first time at the Tokai University Time Trials meet on Apr. 20. A university spokesperson commented, "The lighting system will be useful not only for track races, but also for repurposing as emergency lighting in the event of a disaster."

As much as I'm not a big fan of the wavelights (they are good for entertainment for the masses but I feel like records should be now separated between pre-post wavelights) I have to say that this is a smart and completely understandable move.

Should help with training athletes that are different levels, making it very practical and possibly their track meets will have higher attendance than before.

With the high cost just for renting those, having them permanently could be a win win situation long term too.

Measuring Marathon Courses by Bicycle

http://news.searchina.ne.jp/disp.cgi?y=2013&d=0110&f=column_0110_034.shtml translated by Brett Larner The full marathon is a sport where you compete over 42.195 km, but how do they go about measuring that distance?  Today we're going to look a little bit at how they go about certifying the distance of a marathon. The reality is that major international marathons use a bicycle to measure the distance.  This rule is an international standard, and the same method of measurement is used everywhere.  It was put into place in 1986.  In order to ensure that the same method is used everywhere, a bicycle that meets IAAF specifications must be used for measurement. In the case of Japan's major marathons, to be certain that the distance is correct a provisional measurement is first made.  Before the course is certified using a bicycle the course is measured using a 50 m-long length of wire to determine that it is in fact 42.195 km.  When a bicycle is u...
