A popular form of exercise for people working near or in the Parliamentary Triangle is to do the "bridge to bridge walk/run" of about 5 km around Lake Burley Griffin, crossing the Commonwealth Avenue Bridge and Kings Avenue Bridge, using the paths beside the lake. The walk takes about 1 hour, making it ideal for a lunchtime excursion. This is also popular on weekends. Such was the popularity during the COVID-19 isolation in 2020 that the ACT Government initiated a 'Clockwise is COVID-wise' rule for walkers and runners.
