But there’s a few things you will only know if you’ve completed the 10-mile course. Runners, prepare to look away
9. You can hear the drummers from miles away
Local Samba band Batala Portsmouth is back playing upbeat Afro Brazilian Samba Reggae music at the bottom of Winston Churchill Avenue. You can see them between mile 3 and 4 - but chances are you'll be able to hear them from much further away! Photo: Chris Moorhouse
10. The water showers at Canoe Lake are only useful when it's really hot
When it's hot, there's nothing better than cooling down by running through the water showers by Canoe Lake. But when the weather isn't that nice, you just get a bit damp. Better make the right decision! Photo: Chris Moorhouse
11. Want to avoid the toilet queues? Men, there are urinals round the corner...
There's always a huge queue for the toilet cubicles at the start of the race, but for the male runners there is another option. As one of our staff members points out, there is a set of urinals round the corner by the skate park to make things a bit easier. Photo: Chris Moorhouse
