The fifth staging of The Twilight Ultra takes place at the Redbridge Cycle Centre in East London after another successful year in 2018.
The secure, traffic-free, undulating, tarmac route sees runners covering laps of the cycle circuit and finishing on what will, hopefully, be a balmy summer's evening.
With good parking and spectating facilities, the event features a choice of three distances with start times varying according to the distance you select. Aim high and select the ultra distance and you can always step down to a shorter distance.
Runners will be able to take advantage of well-stocked aid stations on each lap with the availability of hot and cold food and drink.
