The carry will be a 25 ft length so you will always end every multiple of 50 ft at the rower. Time on rower gets shorter as you go on, so first 2minutes (0-2min) should try to get as many meter on the row as possible.
For time: 2500m row *Start with row, every 2 minutes farmers carry(2 DBs). Increase 50ft every 2 minutes until rd 5(250ft) then each round is 250ft until 24min time cap. (Rx 50#/35#)(Rx Masters 35/20) (L1 35#/20#) (L2 25#/15#) (L3 15#/10#)
