In October 2008 I found out I had a place in the 2009 London Marathon. My training progression over the next 7 months went a bit like this, on my longest runs:

02/10/08 – 2.2 miles in 00:21 minutes
05/10/08 – 6.3 miles in 01:09:11
20/11/08 – 6.98 miles in about 1 hr
30/12/08 – 12 miles. No idea of time
10/01/09 – 9.82 miles in 01:29:18
21/02/09 – 13.44 miles in 02:45 (this one should have been my clue!)
30/03/09 – 19.22 miles in 03:25:00 (5.6mph @ 10:40 minute miles)
26/04/09 – 26.2 miles in 04:47:04

December 29th 2009 and I found out I had a place in the 2010 Virgin London Marathon.

01/01/10 – 9.46 miles in 01:18:23
04/01/10 – 9.63 miles in 01:23:17
17/01/10 – 11.47 miles in 01:41:39
15/02/10 – 13.36 miles in 01:56:4
27/02/10 – 16.19 miles in 02:21:51
13/03/10 – 19.22 miles in 02:59:49 (6.4mph @ 9:24 minute miles)
20/03/10 – 20 miles in 03:13:04 (6.22mph @ 9.39 minute miles)
28/03/10 – 18.14 miles in 03:15:52 (5.6 mph @ 10.48 minute miles)
05/04/10 – 16.5 miles in 02:24:40 (6.8mph @ 8.48 minute miles) 

I’ll update this as I do longer runs. Hopefully see some progress and improvement on last time!
