Swimming and Snow

It was snow mixed with rain at 5:30am as I headed for the Northridge Althetic Center in Highlands Ranch. Susan Williams called the set:
100 yds warm-up

200 swim
100 back
200 swim
100 IM
200 swim
100 drill

4 x 25 kick fast on :35
50 Easy on :50

Repeated 2 times

4 x 25 no / 1-breathers with pull gear on :35
50 easy pull on 1:00

200 pull tempo on 2:30

Repeated 2 times

300 (25 Fast, 25 Medium, 25 EZ, 4 times) on 4:30
2 x 200 yds on 2:30
4 x 100 yds (odds easy, evens fast) on 1:30
Repeated 2 times

200 warm down

=4,600 yards (2.6 miles)

I was feeling exhausted on the last set and even missed some intervals...not good. Not sure if it was the altitude, sleep, or lingering effects of the half ironman, but regardless- I need to get the yardage up so that I can easily maintain a 1:15 pace for 10,000 yds.
