Thanks for replying to my comment! Given your PB your are statistically among the 10% fastest Marathon runners. Considering that approximately 0.5 % of the world population have at least once finished a marathon (according to a 2012 study from Runners World) you could expect to be in the Top10 or Top 20 within this community with its ~35k members. So potentially a whale within a marathon subfeed ;-)
The idea was to collect the finisher times in the comments of my respective call (https://steemit.com/sports/@shaka/fastest-marathon-runner-of-all-steemians).

So which finishing time are you aiming for in Berlin? My mid-term goal is to break the 3h frontier in 2017, probably at the Frankfurt Marathon.

Happy running!
