"A brick is doing a training session where you go from a bike ride straight into a run. The idea is get your body accustomed to the feeling of transitioning from one to the other, so that come (Triathlon) race day you know what to expect! Expect this - for it to feel like your feet have bricks strapped to them!" (Source: Uberfit Events).
My 'Brick' session this evening was in the dark at zero degrees centigrade! The bike ride felt REALLY cold! Cycled just over 5.5 miles in 24 minutes. Returned home and stashed the bike and straight out for a 1.5 mile fairly fast paced run (12 mins). Total session lasted 38 minutes. Actually felt great afterwards... The Marathon training must be paying off :-)
