Highs and lows of a 20 mile training run

Pre run:	Have I got everything I need? hydration pack ✅, gels ✅ , podcasts ✅, Garmin and headphones charged ✅, route planned ✅, phone ✅, emergency£2 ✅….  Right let’s do this🏃
Mile 2:	20 miles is a long way, perhaps I could shorten it, do 14 miles now and go out for 6 later? I’m I mentally strong enough to do this, I still have 18 miles to go
Mile 6:	whoop whoop gel time! Also, I get to stop and take in my surroundings but mainly the joy of stopping is quite nice.
Mile 8:	this is really silly, why does anyone want to run a marathon, I still have another 4 miles until I can stop and have another gel
Mile 10:	only mile 10, I know it’s halfway but really it feels like it should be more like 12-14 miles,  still 2 miles before my next gel/stop is this route long enough or am I going to have to reroute
Mile 12:	whoop whoop gel stop!! A gel has never tasted so good!! Oh no it's over too quickly time to get going again and brilliant only 8 miles to go
Mile 13:	what I still have 7 miles to go!!! Gutted
Mile 14:	why on earth did you plan a route which includes a hill at mile 14, you could have gone along the canal again!!
Mile 16:	only 4 miles to go, but in distance, it’s only 3 miles, need to re-route!
Mile 17.5	left turn extend extend
Mile 19:5	another bloody hill, we are going move to the bottom of the hill
Mile 20:	Done IT!!!! To be fair there was a point between mile 6 and 14 where I was kinda in the zone, whilst these were my random thoughts I didn't once think about giving up. The podcasts I listened to this run where: David Tennant does a podcast with James Corden Oxygen Addict with Simone Mitchell Ted Talk - can't remember for the life of me! Marathon Talk - night at the science museum with Martin
