4.2 Easy 12k

Tested the groin twinge with an easy 12k around the Bay - finished with no problems. In he middle tried to judge a 5k section aiming for a very steady 21 minutes but was too relaxed to runiit in 21:30 but felt very easy. Aiming to run most of the marathon at the 21 minutes 5 k pace so I will need to do some more running at this pace in the taper. Will give that pace a try out tomorrow in the SMC 30k.
