I'm looking at upping my weekly mileage a bit starting next month and want to do a 2x day on Wednesdays since I normally take Thursdays as a rest day. Later this spring, I might look at adding a second 2x day per week.
For those of you who do some two-a-day workouts, how do you structure them? More distance in the morning, then a follow up in the evening (so say 3500 am, 2000 pm)? Or do you split them doing speed work in the morning? Looking for any ideas on how to break them up and still make them useful, not junk miles.
Thanks in advance - Kari
