There’s something special about training twice on the same day. I’m not talking about brick sessions, or going for a swim in the morning with a run in the evening. I mean training twice with the same discipline. Recently I have been increasing my running in preparation for the Oldham Way Ultra (now cancelled, obviously), and a few times I’ve been for a run on my own in the morning, and then been for a run with my amazing wife later the same day. Running twice on the same day is hard on the legs, but it also feels great.
In the summer we like to go open water swimming, but a few times I’ve been for a swim in the pool before work, and then been for an open water swim that evening. The shoulders and arms always feel a bit tired, and afterwards I want to eat the whole contents of the fridge.
Commuting by bicycle is one way of training twice in one day, but why don’t you smash it up on your best bike in the morning, and then amble around later the same day on a slower bike (if you own more than one bike).
I would recommend taking it a bit easier than normal, but every once in a while, twice a day training will give you a definite buzz.
However, you might have to wait a couple of months as current government guidance states that you should only go out for one form of exercise per day.
