Do not do any running until the soreness goes away. You can probably do walking without pain You might try a sports massage to go into your glutes and down the calf. This is so that you can ease off the tension from the back down. Tape on the day of the race (as provided by bro Koh Papa) or wear compression socks but be aware that you will need to take this easy, otherwise risk pain mid-way. If you do feel pain during the SCSM, then see if you can rest a little and let the pain go away....then walk with small steps. If you try to run again once pain has set in 'cos you will risk a DNF. Also change your mindset about the time you will get..... and if you want to achieve something, tell runners to please put their rubbish in the bin to keep the route litter free   Look forward to your report . Enjoy the night

Wow! Thank you so much i will try it. 

I took part as well, wanted to run but I ended up walking 4km instead. Wasn’t really expecting much from a fun run actually...  It’s all about queuing, queue to go start pen, queue to run I mean walk, queue to collect medal, queue to collect free gifts oh well

Hope this will help for your running gear, or/and use KT Tape. May your first marathon be easier on the "calves"..
